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
