Marcia buys a dress that is on sale for 15% off it's original price. She uses a store coupon to obtain an additional 10% off the sale price. Marcia pays $91.80 for the dress. What was the original price of the dress?
Accepted Solution
A:
15% off the original price 10% off the sale price Sale price $91.80
First we have to find out the price before 10% discount. (sale price) divided by (1 - percent of sale price)
91.80/(1 -.10) = $102
So, $102 was the price before the 10% discount. Now we need to do the same with the 15% off so that we can get the original price.
