Answer:
f(200) = 116
Step-by-step explanation:
Given the function f(x) = 90 + 0.13(x), and f(200), this means that you have to solve the function by plugging in 200 substituting the x, and solve,
f(200) = 90 + 0.13(200)
f(200) = 90 + 26
f(200) = 116
The f(200) represents the total cost in dollars when driving for 116 miles.
