Question

Paul rented a car for $129 plus $0.25 per mile. The total bill at the end of his trip was $216.50. Use the equation 129 + 0.25x = 216.50 to find the number of miles he drove. Show all the work to solve x.

Answer 1

x = 350

Explanation:

129 + 0.25x = 216.50

Solve for x:

Step 1: Subtract 129 from both sides

129 + 0.25x - 129 = 216.50 - 129

0.25x = 87.5

Step 2: Divide both sides by 0.25

0.25x ÷ 0.25 = 87.5 ÷ 0.25

x = 350

x = 350
