Question

The function c(x)=0.56+50 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 140 miles?

Answer 1

So, when we drive 140 miles, all we have to do is plug in 140 for X.

`C(x)=0.56x+ 50\\C(140)=0.56(140)+50\\C(140)= \$ 128.40`
