Answer 2

Calculation of Fabric Usage

To determine the number of costumes that were made, we need to analyze the given information.

According to the question, 20 meters of fabric were used to make several identical costumes, while 12 meters of fabric were used to make several identical dresses. It is also mentioned that the number of costumes is one more than the number of dresses.

Let's assume the number of dresses is x. Therefore, the number of costumes would be x + 1.

To find the number of costumes, we need to compare the fabric usage for costumes and dresses.

The fabric usage for costumes is 20 meters, and the fabric usage for dresses is 12 meters.

To find the number of costumes, we can set up the following equation:

20 / x = 12 / (x + 1)

Let's solve this equation to find the value of x.

To do this, we can cross-multiply:

20(x + 1) = 12x

Simplifying the equation:

20x + 20 = 12x

Subtracting 12x from both sides:

20x - 12x + 20 = 0

Simplifying further:

8x + 20 = 0

Subtracting 20 from both sides:

8x = -20

Dividing both sides by 8:

x = -20 / 8

Therefore, the number of dresses is approximately -2.5.

However, it is not possible to have a negative number of dresses. Therefore, there seems to be an error in the given information or calculation.

Please double-check the information provided and ensure that it is accurate.
