Question

answers-
$1.50
$3.75
$4.25
$5.25

Answer 1

The rate of change of the cost in dollars with respect to the number of miles is the coefficient of x in the function. In this case, the coefficient of x is 1.5.

Therefore, the rate of change of the cost in dollars with respect to the number of miles is $1.50.

So, the correct answer is $1.50.
