g m = −0.05m + 12.1The given function g models the number of gallons of gasoline that remains from a full gas tank in a ca rafter driving m miles. According to the model, about t how many gallons of gasoline are used to drive each mile?

Explanation

Option A is correct. The function g(m) = -0.05m + 12.1 models the amount of gasoline remaining in the tank after driving m miles. Here, -0.05 is the coefficient of m, which indicates the change in gallons per mile. Specifically, it shows that each mile driven results in a reduction of 0.05 gallons of gasoline. Therefore, 0.05 gallons are used per mile. Option B is the total gasoline capacity of the tank, while Options C and D are unrelated to the rate of gasoline usage.
