I had 3 sheets of stickers. I gave 20 stickers from each sheet to my students and I have 12 total stickers left. How many stickers were originally on each sheet.
Let's assume that there were originally x stickers on each sheet.
Since you had 3 sheets of stickers, the total number of stickers you had initially is 3x.
You gave 20 stickers from each sheet, so the total number of stickers given to students is 20 * 3 = 60.
Now, you have 12 stickers left, so the equation becomes:
3x - 60 = 12
Adding 60 to both sides of the equation:
3x = 72
Dividing both sides of the equation by 3:
x = 24
Therefore, there were originally 24 stickers on each sheet.
To solve this problem, let's break it down step by step:
Step 1: Determine the total number of stickers given to the students.
Since 20 stickers were given from each of the 3 sheets, the total number of stickers given to the students is 20 * 3 = 60 stickers.
Step 2: Calculate the original total number of stickers.
Since there are 12 stickers left, and these stickers were not given to the students, the original total number of stickers is 60 + 12 = 72 stickers.
Step 3: Divide the original total number of stickers by the number of sheets.
Since there were 3 sheets, we can divide the original total number of stickers (72) by 3 to find the number of stickers on each sheet.
72 / 3 = 24 stickers.
Therefore, there were originally 24 stickers on each sheet.
