Question

A car manufacturer claims that their car can get 32 miles per gallon minus the speed

factor. This can be modeled by the linear equation f(x) = 32 -0.15x where f(x)
represents the miles per gallon and x is the mph. What would be the predicted miles
per gallon for a car going 60 mph using this equation?
Type your answer.

Answer 1

23 mpg

Explanation:

We simply need to evaluate the given function at the speed requested (60 mph):

`f(x)=32-0.15\,x\\f(60)=32-0.15\,(60)\\f(60)=23\,\,mpg`
