Answer:
the total number of stickers is 24
Explanation:
The computation of the total number of stickers is shown below
Let us assume the total no of stickers be x
Now as per the question, the equation is
3(x - 20) = 12
3x - 60 = 12
3x = 12 + 60
3x = 72
x = 24
Hence, the total number of stickers is 24
