Suppose you purchase sunglasses that are regularly priced at $87.20. They are on sale for 30% off, and you have a coupon for 10% off the sale price of any item. What is the final price of the sunglasses?
Okay so the answer would be D. Because when you add 30% and 10% that is 40%. Then you subtract 40% from 60%. When you do that, you multiply 60% and $87.20, you get $52.32--40% off of $87.20.
