Mr turner sent his car to the workshop for repair work as well as to change 4 tires. Mr turner paid $1035 in all. The repair work cost 5 times the price of each tire. The mechanic told Mr. turner that the repair work cost $500. Explain the mechanic’s mistake

Let the cost for work be w. Let the cost for each tire be t. We're given;

1. w = 5t
2. w + 4t = 1035

Substitute equation 1 into equation 2:
(5t) + 4t = 1035

Type this equation into our search engine, and we get:
t = 115

Substitute this into equation (1):
w = 5(115)
w = 575

The mechanic underestimated the work cost.
