Answer:
The answer is 32.5%, or C.
Step-by-step explanation:
If the item was $100, when you take 25% off the item would cost $75. The store owner took off another 10% AFTER they had already lowered the price. So, you would take 10% off $75 which would be $67.5. You cannot add the prices because they would would get a different answer, if you add the percentages you’d get 35% and 35% off of an $100 item would be a different price.
Hope this helped!
