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
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:
