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?

C = 38 × (h)

Step-by-step 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

C(h) = (38 contestants/hour)×h

Step-by-step 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
