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.

Answer 1

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.
