Problem

The function c(x) = 0.47x + 20 represents the cost (in dollars) of a one-day truck rental when the truck is driven x miles.What is the truck rental cost when you drive 80 miles?​

Solution

For this case we just need to replace into the function given by:

c(x) = 0.47x + 20

For this case we just need to replace x=80 mi and we got:

c(80)= 0.47*80 +20= 37.6 +20= 57.6
