Step-by-step explanation:

Here os the correct question:

Stephanie saw in an ad in the paper that her favorite kind of perfume was on sale for 25% off. If the sale price was $15, what was the original price of the perfume?

Let the original price of the perfume be y.

Since we are told that 25% is off, that means that 25% has been deducted from the original price. This can be written as:

y - (25% of y) = $15

y - (25/100 × y) = $15

y - 0.25y = $15

0.75y = $15

Divide both side by 0.75

0.75y/0.75 = $15/0.75

y = $20

The original price of the perfume is $20
