Rodrigo buys a jacket that is on sale for 1/4 off the origonal price of 80$. He has a coupon for and additional 10% off. How much does Rodrigo pay for the jacket?
$80 x 1/4 =$20 - Discount on the jacket.
$80 - $20 = $60 - Sale price of the jacket
$60 - [10% x $60] =
$60 - [0.10 x $60] =
$60 - $6.00 = $54 - The price of the jacket after the discount and 10% coupon.
Price after off =80- 1/4 * 80 = 80-20 = $60
Coupon discount = 60*10/100 = $6
So, he will have to pay, 60-6 = $54
Original price 80 dollars
less 25% 80 - 80(.25) = 60 dollars now take an additional 10% off
60- 60(.1) = $ 54.00
