Answer:
s = 80.
See below for the meaning.
Explanation:
Let the total number of sheets = s. Therefore
(5/8) * s = 50 Multiply both sides by 8/5
(8/5) * (5/8) * s = 50 * (8/5) Cancel the left, multiply by 8/5 on the right
s = 50 * 8/5
s = 400/5
s = 80
The answer is 80 sheets. It means that when you took the roll of paper towels out of the wrapper it was in when you bought it, there were 80 sheets in the roll. It also means that Madeleine has 30 sheets left.
