Question

Jenna gives away 96 flyers over a 4-hour period. If the number of flyers she is able to give away per hour remains the same, which proportion can be used to find x, the number of flyers that she would give away over a 7-hour period?

A. 96/4 = x/7
B. 4/96 = 7/x
C. 96/7 = x/4
D. 7/x = 4/96

Answer 1

The correct proportion to find out how many flyers Jenna would give away over a 7-hour period, when she gives away 96 flyers over 4 hours, is A. 96/4 = x/7. Solving this gives x = 168 flyers.

Step-by-step explanation:

The student is looking to solve a proportion to find the number of flyers Jenna would give away over a 7-hour period, given she gives away 96 flyers in a 4-hour period. To set up the correct proportion, we want to compare flyers given away (96) to the time it took (4 hours) and equate it to the flyers given away (x) over a different time period (7 hours). Therefore, the correct proportion is A. 96/4 = x/7. This states that the flyers per hour are the same in both cases. You can solve for x by cross-multiplying to get 4x = 672 (96 times 7), then divide both sides by 4 to find that x equals 168 flyers over 7 hours.
