Problem Analysis

To solve this problem, we need to determine the number of chairs that were repaired using the given information. We know that 75 meters of fabric were purchased for the repair, and each chair requires 4 meters of fabric. After the repair, there were 15 meters of fabric remaining. We need to find the number of chairs that were repaired.

Solution

Let's assume the number of chairs repaired is x. Since each chair requires 4 meters of fabric, the total fabric used for the repair is 4x meters. We also know that there were 15 meters of fabric remaining after the repair. Therefore, we can set up the following equation:

75 - 15 = 4x

Simplifying the equation, we have:

60 = 4x

To find the value of x, we divide both sides of the equation by 4:

60 / 4 = x

x = 15

Therefore, 15 chairs were repaired.

Answer

The number of chairs that were repaired is 15.
