Select the correct answer from the multiple choice below.

Sully's car has an average fuel economy of 28 miles per gallon. The capacity of the fuel tank is 16 gallons. If Sully completely fills the tank, which function represents the number of miles the car can go without refueling in terms of the gallons of fuel it consumes? (Hint: Convert the car's fuel tank capacity in gallons to the number of miles the car can travel.)

A. y=265-16x

B. y=448-16x

C. y=448-28x

D. y=16-28x

E. y=256+16x

(Could easily be wrong, Math is not my strongsuit) I think its D, because you are suppose to convert the fuel tank capacity to the miles per gallon.

Jaylan Levy · Answer 2

28 mi/gallon

In the beginning Sully has 16 gallons of fuel, and can drive

16 gallons*28 mi/gallons=448 mi

At the x=0, y=448 mi - this is y-intercept

28 mi/h is a slope (for one h - 28 mi, for 2 h - 28*2 and so on)

The function is y=448-28x.

Answer is C.
