Question

The contents of the fuel tank of a car can be modeled by the function g(x)= -0.04x + 10, where x is in miles driven and g(x) represents the amount of fuel remaining in the tank in gallons. Kira traveled 150 miles. How many gallons does she have left in her car?

A. 6
B. 4
C. 8
D. 10

Answer 1

The answer is B.4. It is 4 because you have to multiply -0.04 x 150 since the x after -0.04 represents miles driven which was 150 and then add 10 which then you get 4
