A t-shirt originally priced at $16 was reduced after a sale. After a coupon had been applied, James paid $11.20 for a new t-shirt. By what percent was the shirt discounted?

Answer 1

$11.20 = ($16.00)x

x = ($11.20) / ($16.00) = 0.70

He paid 0.70 times the original price, which means he paid 70% of the original price, so the discount had to be 30%.
