To solve this problem, we need to determine the value of x, which represents the number of buttons on the second type of shirt.
Let's break down the information given:
Number of shirts with 3 buttons: 200
Number of shirts with x buttons: 200
Total number of buttons: 1600
We can set up the equation as follows:
Number of shirts with 3 buttons * Number of buttons per shirt + Number of shirts with x buttons * Number of buttons per shirt = Total number of buttons
200 * 3 + 200 * x = 1600
Let's simplify and solve for x:
600 + 200x = 1600
To isolate x, we subtract 600 from both sides of the equation:
600 + 200x - 600 = 1600 - 600
200x = 1000
To solve for x, we divide both sides of the equation by 200:
x = 1000 / 200
x = 5
The value of x is 5.
#### 5
The answer is: 5
