Answer 2

Problem Analysis

We are given that 5 meters of fabric are used for a dress and 2 meters of fabric are used for a shirt. From a total of 114 meters of fabric, dresses and shirts are made. We know that 18 dresses were made. We need to determine how many shirts were made.

Solution

To solve this problem, we can set up a system of equations based on the given information.

Let's assume the number of shirts made is represented by x.

The total amount of fabric used for dresses can be calculated by multiplying the number of dresses (18) by the amount of fabric used for each dress (5 meters):

Total fabric used for dresses = 18 * 5 = 90 meters

The total amount of fabric used for shirts can be calculated by multiplying the number of shirts (x) by the amount of fabric used for each shirt (2 meters):

Total fabric used for shirts = x * 2

According to the problem, the total amount of fabric used for both dresses and shirts is 114 meters. Therefore, we can set up the following equation:

Total fabric used for dresses + Total fabric used for shirts = Total fabric available

90 + x * 2 = 114

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

90 + 2x = 114

Subtracting 90 from both sides:

2x = 24

Dividing both sides by 2:

x = 12

Therefore, 12 shirts were made.

Answer

The number of shirts made is 12.
