Answer:
$103
Step-by-step explanation:
You want the cost of driving a rental car 200 miles when the cost function is C(x) = 0.4x +23 for x miles driven.
Put the mile value where x is in the function and do the arithmetic.
C(200) = 0.4(200) +23
C(200) = 80 +23 = 103
The cost of driving the car 200 miles is $103.
