Question

Prompt

The gas mileage of a certain car is 35 miles per gallon when driven on the highway. If the car begins with 10 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}{35} - 10

f (d) = d - 10

f (d) = 10 - \frac{d}{35}

f (d) = 10 - d
