Question

A singing competition is auditioning 38 contestants each hour for the next h hours. Which equation can be used to find the total number of contestants, C, that audition in h hours?

Answer 1

C(h) = (38 contestants/hour)×h

Explanation:

Let C(h) = number of contestants audited in h hours. The equation describing this situation is a linear one; in other words, C(h) is directly proportional to h:

C(h) = (38 contestants/hour)×h

Answer 2

C = 38 × (h)

Explanation:

If we have 38 contestants per hour, then the number of hours (h) multiplied by 38 people, will tell us the total amount of people who auditioned (C) over h hours.

Total contestants = 38 people for every hour. C = 38h
