Answer:
John had drove 162 miles is what you need to say.
Explanation:
lets say miles = x 20.95 + .72x = 137. 59 = step 1 ) eliminate base fee both sides through opposite subtraction = 20.95 - 20.95 + .72x = 137. 59 -20.95 = .72x = 137. 59 -20.95 = .72x = 116.64 = step 2) eliminate cost per mile through division to both sides to find full mileage = 116. 64/ .72 = 162 miles and x = 162 as proved in reverse 162 * .72 = 116 64 charges of total found earlier therefore John had drove 162 miles is what you need to say.
