Stephanie is helping her band collect money to fund a field trip.
The band decided to sell boxes of chocolate bars. Each bar sells
for $1.50 and each box contains 20 bars. Below is a partial table
of monies collected for different numbers of boxes sold.
Boxes Sold (b) Money Collected (m)
1 $30
2 $60
3 $90
4 $120
5 $150
6 $180
7 $210
8 $240
1.) Complete the table above for all values of m.
2.) Which is the independent variable?
3.) Which is the dependent variable?
4.) Write an equation for the amount of money, m, that will be
collected if b boxes of chocolate bars are sold.
5.) Graph the equation using the ordered pairs from the table
above.
(Don’t forget to label your axes and increments!)
6.) How much money will be collected if 100 boxes of chocolate
bars are sold?
7.) The band collected $1530 from chocolate bar sales. How
many boxes did they sell?
Answers
Answer:
Step-by-step explanation:
for the table for every box just add 30 more dollars 1.5x20=30
The independent variable is I believe the box of candy bars
And the dependent is the money collected
m=30b since a 1 box is 30 dollars
m=30(100)
m=3000 they will make 3,000 dollars with 100 boxes
1530=30b
/30. /30
51=b
51 boxes of chocolate bars when they make $1530 dollars
Graph will be below
