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.
