PART A
WT = 30
30 = 3HF + 2FA
30 = 3x + 2y
2y = 30 - 3x
y = 15 - 3/2x
0 = 15 - 3/2x
3/2x = 15
x or EH = 10
y = 15 - 3/2(10)
y = 15 - 15
y or FA = 0
Okay so this problem doesn't make sense because FA cannot = 0. I know I did the first part right - change of variables. I'm just not sure if we can use the information in part b to answer part a... Anyway, I hope this helps!

Meade gave 1/7 of a candy bar to Max and then ate 2/5 of the candy bar himself. What fraction of the candy bar is left?
There is ______ of the candy bar left
Let's break this problem into a few steps:
First, Meade gave 1/7 of candy to Max⇒ Amount of Candybar: Candy - (1/7)Candy = (6/7)Candy
Second, Meade ate 2/5 of the candy⇒ Amount of Candy left:
Total amount of candy - (2/5) * Total amount of candy
= (6/7) Candy - (2/5) *(6/7)Candy
= (1 - (2/5)) * (6/7) Candy
= 3/5 * 6/7 = 18/35 Candy
Thus there is 18/35 of the candy left.

Your annual salary is $60,000. What is your semimonthly salary? What is your biweekly salary?
Answer:
2,307.69 per biweekly paycheck and 2,500 per semi monthly paycheck
Step-by-step explanation:
If you didn't already know, monthly pay has 12 paychecks, semi-monthly pay has 24 paychecks, biweekly pay has 26 paychecks, and weekly pay has 52 paychecks. If you break down 60k into these paychecks, here are the results: $60,000/12 equals $5,000 (monthly pay) $60,000/24 equals $2,500 (semi-monthly pay)

4 Jackson's mom limits the amount of time he is allowed to play video games. After
Jackson plays for 9 minutes, his mom tells him that he has used up 30% of his time.
How many more minutes can Jackson play before he uses all of his time?
Show your work.
Answer Jackson can play
more minutes.
Answer:
Jackson can play for 21 more minutes.
Step-by-step explanation:
If 9 minutes = 30% or 0.3
then we can set up a ratio to cross multiply.
(9/30) = (x/100)
then croos multiply and divide to isolate and solve for x.
(9 * 100) / 30 = 30
That means 100% of Jackson's time is 30 minutes.
30 - 9 = 21. So jackson can play for 21 more minutes before he uses all of his time.
But by the time he figures all of this out he'll probably have to turn it off anyways :)
Hover– High helicopters manufacturers radio – control toy helicopters. They have their quality control down to a point we’re only one in 100 built could be defective and returns for repair at a cost to the company of $50. At a profit margin of $10 per unit, what would their profit be per unit after selling 200 copters?
If a profit margin is $10 per unit, what would their profit be per unit after selling 200 copters is $9.40.
Profit per unitFirst step
There are 2 defectives in 200 copters
Total profit=[(200-2)×$10]-($50×2)
Total profit=(198×$10)-$100
Total profit=$1,980-$100
Total profit=$1,880
Second step
Profit per unit=$1,880/200
Profit per unit=$9.40
Therefore their profit be per unit after selling 200 copters is $9.40.

The unit rate per munchkin is $0.22.
What is Division?
Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
The cost of 25 munchkins cost $5.46, therefore, the unit rate of each munchkin can be written as,
[tex]\text{Cost of unit munchkin} = \dfrac{\text{Total cost of munchkins}}{\text{Number of munchkins}}\\\\\text{Cost of unit munchkin} = \dfrac{\$5.46}{25}=\$0.2184 \approx \$0.22[/tex]

Topic: Labor Economics.
Need solution for tasks 4 4.1 4.2 4.3
The curves of the labor market are illustrations of demand and supply, and the curves are all linear functions
4.1: The graph of the curves of the labor marketThe equations are given as:
D = 36 - 2W
S₁ = 9 + W ---- domestic (i.e. without immigrants)
S₂ = 10 + 2W ---- total (i.e. including immigrants)
See attachment for the graph
4.2: The equilibrium wage rate before immigrationThis is the point of intersection between the curves of S₁ and D.
From the graph, we have:
(W, D) = (9,18)
Hence, the equilibrium wage rate before immigration is $9, and the number of workers that would be hired is 18
4.3: The equilibrium wage rate after immigrationThis is the point of intersection between the curves of S₂ and D.
From the graph, we have:
(W, D) = (6.5,23)
Hence, the equilibrium wage rate after immigration is $6.5, and the number of workers that would be hired is 23
4.3.1: Number of domestic workers hiredSubstitute 6.5 for W in S₁ = 9 + W
S₁ = 9 + 6.5
S₁ = 15.5
Remove decimal
S₁ = 16
Hence, the number of domestic workers that would be hired is 16
4.3.1: Number of immigrants hiredSubstitute 6.5 for W in S₂ = 10 + 2W
S₂ = 10 + 2 * 6.5
S₂ = 23
Subtract S₁ = 16 from S₂ = 23
Immigrants = 23 - 16
Immigrants = 7
Hence, the number of immigrants that would be hired is 7
