Stuart bought a sweater that was on sale for 30% off the regular price. He also had an additional 25% off coupon. If the original price was $30, how much did he pay for the sweater?

Step-by-step explanation:

The original price of the sweater that Stuart bought was $30.

The sweater was on sale for 30% off the regular price. This means that the amount of money that was removed from the original price is

30/100 * 30 = 0.3 * 30 = 9

The price at which the sweater was offered for sale would be

30 - 9 = $21

He also had an additional 25% off coupon. The value of the coupon would be

25/100 * 21 = 0.25 * 21 = $5.25

Therefore, the amount that he paid for the sweater would be

21 - 5.25 = $15.75
