Aida bought a costume box containing 50 costumes for $300. She sold all of the costumes and made a $250 profit. She sold all of the costumes for the same price. Use the equation 50c-300=250, where c is the selling price of each costume. What was the selling price of one costume in dallars?
Answer:$11
Step-by-step explanation: 50c - 300= 250
Add 300 to both sides
Divide both sides by 50

Answer:
42.3
Step-by-step explanation:
Substitute in values[tex]3.6\times (3)+4.5\times (7) = 10.8+31.5=42.3[/tex]The high attendance at this year's Vacation Bible School at Highland Church was one hundred
seven children. This was twenty-three less than twice the number that attended last year. How many
children attended last year?
Answer: 65
Step-by-step explanation:
Given:
This year's attendence = 107
Let last year's attendence = x
Create an equation an solve for x:
2x - 23 = 107
2x = 107 + 23
2x = 130
x = 130/2
x = 65
Therefore, 65 children attended last year's Vacation Bible School
One year, sales increased by 15%. The following year sales increased by 18%. Calculate the overall percentage increase in sales.
Answer:
35.7%
Step-by-step explanation:
Sales increase in Year 1
Let the original sales be xSales has increased by 15%Therefore, new sales will be :Original sales + Original sales x 15%⇒ x (1 + 15%)⇒ x (1 + 0.15)⇒ x (1.15)⇒ 1.15xSales increase in Year 2
From Year 1, it has increased by 18%New sales will be :Year 1 sales + Year 1 sales x 18%⇒ 1.15x (1 + 18%)⇒ 1.15x (1 + 0.18)⇒ 1.15x (1.18)⇒ 1.357xOverall Increase
Year 2 sales - Original sales / Original sales1.357x - x / x0.357x / x0.357Decimal to % ⇒ x 100%0.357 x 100%35.7%Let the sales be known as "a".
Given statement:
One year, sales increased by 15%.
This can be written as:Year 1 = a + (a × 15%)Step-1: Evaluate the percentage⇒ Year 1 = a + (a × 15%)⇒ Year 1 = a + (a × 15/100)Step-2: Multiply the terms inside the parentheses⇒ Year 1 = a + (a × 15/100)⇒ Year 1 = a + (15a/100)Step-3: Open the parentheses⇒ Year 1 = a + (15a/100)⇒ Year 1 = 100a/100 + 15a/100Step-4: Add the like terms;⇒ Year 1 = 100a/100 + 15a/100⇒ Year 1 = 115a/100Next year (Year 2):Given statement:
The following year sales increased by 18%.
This can be written as:Year 2 = Year 1 + (Year 1 × 18%) Step-1: Substitute the amount of sales in year 1:⇒ Year 2 = Year 1 + (Year 1 × 18%) ⇒ Year 2 = 115a/100 + (115a/100 × 18/100)Step-2: Simplify the fractions in the parentheses:⇒ Year 2 = 115a/100 + (115a/100 × 18/100)⇒ Year 2 = 115a/100 + (23a/20 × 9/50)Step-3: Multiply the fractions in the parentheses:⇒ Year 2 = 115a/100 + (23a/20 × 9/50)⇒ Year 2 = 1150a/1000 + (207a/1000)Step-4: Open the parenthesis:⇒ Year 2 = 1150a/1000 + (207a/1000)⇒ Year 2 = 1150a/1000 + 207a/1000Step-5: Add the fractions:⇒ Year 2 = 1150a/1000 + 207a/1000⇒ Year 2 = 1357a/1000Overall percentage increase:Formula:
Overal percentage increase = (Sales in year 2 - Original sales) × 100
Step-1: Substitute the values in the equation:⇒ Overal percentage increase = (Sales in year 2 - Original sales) × 100⇒ Overal percentage increase = (1357a/1000 - a) × 100Step-2: Simplify the expression in the parentheses:⇒ Overal increase = (1357a/1000 - a) × 100⇒ Overal increase = (1357a/1000 - 1000a/1000) × 100⇒ Overal increase = (357a/1000) × 100Step-3: Open the parentheses and simplify:⇒ Overal increase = (357a/1000) × 100⇒ Overal increase = 357a/10 ⇒ Overal increase = 35.7aStep-4: Determine the overal increase in percentage:⇒ Overal increase = 35.7a⇒ Overal percentage increase = 35.7%Therefore, the overal increase in percent is 35.7%.

Answer:
C
Step-by-step explanation:
The area of a square is the square of the side length. When the side length x=2.5 cm, the area is the square of that value.
__
A(x) = x²
A(2.5 cm) = (2.5 cm)² = 6.25 cm²
_____
Additional comment
The "square" of a variable is that variable to the second power. The terms 2x or 4x are linear terms with the variable to the first power, do not represent the area of a square.
The equation A(x) = 4x² introduces a multiplier of 4 that is not applicable to the area of a square based on side length. (The formula might be useful if x represents the distance from one side to the center of the square, the radius of an inscribed circle, for example.)
complete the function table and write the function rule
Answer:
6 and -22
Step-by-step explanation:
See attached image.
The function rule for the linear function is y = y = x - 12
The missing values are: x = 6; and y = -22.
What is a Linear Function Rule?Where, m is the average rate of change, and b is the initial value when x is 0, therefore, a linear function rule is given as, y = mx + b.
Find m and b using the table of values given.
Using (32, 20) and (14, 2):
Average rate of change (m) = change in y / change in x = (20 - 2)/(32 - 14)
Average rate of change (m) = 18/18 = 1.
Find b by substituting m = 1 and (x, y) = (14, 2) into y = mx + b
2 = 1(14) + b
2 = 14 + b
2 - 14 + b
-12 = b
b = -12
Write the rule of the linear function by substituting m = 1 and b = -12 into y = mx + b
y = 1(x) + (-12)
y = x - 12
Find the missing values on the table
Fourth Row: when y = -6
-6 = x - 12
-6 + 12 = x
x = 6
Last Row: when x = -10
y = -10 - 12
y = -22
Therefore, the function rule for the linear function is y = y = x - 12
The missing values are: x = 6; and y = -22.

A rectangle measures 4 3/4 inches by 1/3 inches . What is the area ?
Answer:
A = [tex]\frac{1}{4}[/tex] in²
Step-by-step explanation:
the area (A) of a rectangle is calculated as
A = lb ( l is the length and b the breadth ) , then
A = [tex]\frac{3}{4}[/tex] × [tex]\frac{1}{3}[/tex] ( cancel 3 on numerator/ denominator )
= [tex]\frac{1}{4}[/tex] × 1 = [tex]\frac{1}{4}[/tex] in²
The sections of a spinner are divided into five
equal sections and are lettered A to E. Myla spins
the pointer of the spinner once and rolls a number
cube numbered 1 to 6. What is the probability of
landing on B and rolling an even number?
Answer: 0.066, or a 6.6% Statistical Probability.
Step-by-step explanation:
When dealing with Statistical Probability, you are attempting to find the theoretical chance of an action occuring.
With the two actions described, one being a wheel with five set outcomes, and a dice with six set outcomes, you can find the probability of random numbers/outcomes by taking
[tex]\frac{1}{6} \\and\\\frac{1}{5}[/tex]
1/6 being number cube, 1-2-3-4-5-6
and
1/5 being spinner. A-B-C-D-E
In the Event, (made up by actions), it is described that The Cube AND Spinner are rolled and spun at random.
Also, The description asks: what is the probability of landing on B and rolling an even number?
So, the 1/6 chance of the dice becomes 1/3, or .33 or 33%.
And, the 1/5 chance for the spinner stays the same, because it is a single unit. So, probability of landing on B is still 1/5, or .2 or 20%.
When two actions are present in an Event, you are to procedurally multiply the outcomes by the decimal percentage, fraction, or actual percentage, to find the chance of occurence.
In this scenario, I used .2 x .33 and got 0.066
Which, equals 6.6%
I found this by multiplying the decimal percentage by 100, to scale the chance on a 100/100 based scale. In this case, the multiplier on the numerator is .066 ... creating 6.6/100, or .066 or 6.6%

Ten friends played slot machines in Las Vegas. Their average loss was $60 and the standard deviation of the loss was $10. What does the standard deviation of $10 mean
Using it's concept, it is found the standard deviation of $10 means that most students spent within $10 of the mean of $60 on the slot machines.
What is the standard deviation of a data-set?The standard deviation is given by the square root of the sum of the differences squared of each observation and the mean, divided by the one less than the number of values.It represents by around how much the distribution varies around the mean.Hence, in this problem, the standard deviation of $10 means that most students spent within $10 of the mean of $60 on the slot machines.

Two angles are complementary.The larger angle is 30 degrees more than 4 times the smaller
angle find the measure of each angle
Define variables
Answer:
Step-by-step explanation:
Remark
2 angles are complementary means that 2 angles add up to 90°. That is the guiding princeple behind the problem.
Givens
Let the smallest angle = x
Let the largest angle = 4x + 30
Equation
4x + 30° + x = 90° Combine like terms on the left
Solution
5x + 30 = 90 Subtract 30 from both sides.
5x + 30 - 30 = 90 - 30 Combine
5x = 60 Divide both sides by 5
5x/5 = 60/5
