Can somebody please help me
adelina 88 [10]
The answer would be 232.50
You would take the 232.50 and take 60% off so you would do 232.50 times .60 that gives you 139.50. You subtract the 139.50 from the 232.50 which would give you 93. Then you subtract the 25 from the 93 for the gift certificate..that would give you $68 as the total amount. So the answer would be that the original price of the shoes was $232.50
