The dress store is having a sale where all merchandise is 1/4 off. A woman buys $24 of merchandise at the sale price.

The answer isn't complete, so i'll assume the question is 'What was the original price:

We have the original price (X), 25% off, and a final price of $24. This gives the equation:

X * (1 - 0.25) = 24

Which can be rearranged into:

X = 24 / (0.75) = $32
