Exercise 7 Page 91

Calculate the function's value when x=250.

C

Practice makes perfect

We are asked to find the total rental cost for a car driven 250 miles. The variable x represents the number of miles the rented car is driven. Moreover, f(x) represents the total rental price for a car. To find the answer, we will substitute 250 for x in the given function.

f(x)=0.35x+49
f( 250)=0.35( 250)+49
f(250)=87.5+49
f(250)=136.5

The total cost is $ 136.50, which corresponds to option C.
