Question

Let n represent the time in hours for the service call and C represents the total cost in dollars. Write an equation that relates C and n

Answer 1

C(n) = pn

Explanation:

Given :

n = time in hours for service call

C = total cost

Total cost = unit cost per hour * time in hours

If unit cost per hour = p

Hence,

C(n) = p * n

C(n) = pn
