Question 3

Lester Moy bought two new Michelin Tires for his car at $170.55 per tire. He was also charged $4.95 per tire for mounting, $2.65 per tire for valves, and $3.99 per tire for balancing. What was Lester's final bill?

Accepted Answer

The total cost for two tires is $170.55 x 2 = $341.10. The additional charges per tire are $4.95 (mounting) + $2.65 (valves) + $3.99 (balancing) = $11.59. For two tires, the additional charges are $11.59 x 2 = $23.18. Therefore, the final bill is $341.10 + $23.18 = $364.28.
