Alicia bought a prom dress that originally cost $110 after she used coupon she spend $82.50 on the dress, find percent discount

Question

that she recieved 

Answer 1

Take the original cost of the dress and subtract the final price to get the total discount received with the coupon. Then you divide the discount by the original cost to get the percentage of discount.

 

So...

$110-$82.50=$27.50

$27.50/$110=.25 or 25%

 

Alternately you can just divide the discounted price by the original and subtract that answer from 100 percent to get the final answer.

So...

$82.50/$110=.75

1.00-.75 =.25 or 25%
