Answer 2

Problem Analysis

To solve this problem, we need to find the amount of fabric that was initially available in the store. We are given that on the first day, 32% of the fabric was sold, and on the second day, 7% of the fabric was sold. After these two days, there is 274.5 meters of fabric remaining. We need to determine the total amount of fabric that was initially in the store.

Solution

Let's assume that the total amount of fabric initially in the store is x meters.

On the first day, 32% of the fabric was sold, which means 68% of the fabric remains. Therefore, the amount of fabric remaining after the first day is 0.68x meters.

On the second day, 7% of the remaining fabric was sold, which means 93% of the fabric remains. Therefore, the amount of fabric remaining after the second day is 0.93 * 0.68x meters.

According to the problem, after these two days, there is 274.5 meters of fabric remaining. So we can set up the following equation:

0.93 * 0.68x = 274.5

To find the value of x, we can solve this equation:

0.93 * 0.68x = 274.5
0.6324x = 274.5
x = 274.5 / 0.6324
x ≈ 434.03

Therefore, the total amount of fabric that initially entered the store is approximately 434.03 meters.

Answer

The total amount of fabric that initially entered the store is approximately 434.03 meters.
