Question

Opening Exercise: Isaiah sold candy bars to help raise money for his scouting troop. Is the amount of candy bars sold proportional to the money Isaiah received? How do you know?

a) Yes

b) No

Answer 1

Yes, the amount of candy bars sold is proportional to the money Isaiah received. There is a constant ratio between the number of candy bars sold and the money received.

Step-by-step explanation:

Yes, the amount of candy bars sold is proportional to the money Isaiah received. When two quantities are proportional, they have a constant or fixed ratio between them. In this case, the number of candy bars sold and the money received have a constant ratio.

For example, if Isaiah sells 10 candy bars for $5, then the ratio of candy bars to money is 10:5, which can be simplified to 2:1. This means for every 2 candy bars sold, Isaiah receives $1.

By calculating the ratio for different amounts of candy bars sold, you can verify that the ratio remains constant, indicating a proportional relationship between the number of candy bars sold and the money received.
