Question

Gerry bought tires for his car. They costed 80 dollars each and should be replaced every 64000km. He drove 4000km on his vacation. What was the cost of the wear on his tires?

Answer 1

The cost of the wear on Gerry's tires is $5.

Step-by-step explanation:

To calculate the cost of the wear on Gerry's tires, we need to determine how many times he needs to replace them based on the distance driven. The cost of wear on the tires can be calculated by multiplying the cost of each tire by the number of times they need to be replaced. Let's calculate:

1. First, we need to find the number of times Gerry needs to replace his tires. Since his tires need to be replaced every 64000 km, we can divide the total distance driven (4000 km) by the replacement distance (64000 km) to get the number of times: 4000 km ÷ 64000 km = 0.0625.
2. Next, we multiply the number of times Gerry needs to replace his tires by the cost of each tire: 0.0625 × $80 = $5.

Therefore, the cost of the wear on Gerry's tires is $5.
