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
