Question 95

This model can be used to predict the fuel consumption of a car, y y\,y miles per gallon, for a car travelling at x x\,x miles per hour.

y=60−0.025(x−40)2 y = 60 - 0.025(x - 40)^2 y=60−0.025(x−40)2

Calculate the fuel consumption, in miles per gallon, of a car travelling at 60 miles per hour.
