Question

Prompt

The gas mileage of a certain car is 22 miles per gallon when driven on the highway. If the car begins with 8 gallons of gas in the tank, which function predicts the amount of gas remaining in the tank,

f (d)

, after the car is driven

d

miles on the highway?

f (d) = \frac{d}{22} - 8

f (d) = d - 8

f (d) = 8 - \frac{d}{22}

f (d) = 8 - d
