To solve this problem, we need to determine the value of x, which represents the number of inches of gift wrapper used per gift box.
Let's break down the information given:
Number of inches of gift wrapper used per day: 90
Number of gift boxes wrapped every 3 days: 15
We can set up the equation as follows:
Number of inches of gift wrapper used per day * Number of days = Number of inches of gift wrapper used in total
90 * 3 = 270
Let's set up another equation:
Number of inches of gift wrapper used in total / Number of gift boxes wrapped = Number of inches of gift wrapper used per gift box
270 / 15 = x
Let's simplify and solve for x:
270 / 15 = x
18 = x
The value of x is 18.
#### 18
The answer is: 18
