So $39.50 is the price when you are paying full price, which can be represented by 100%. If you’re paying 25% less, than you are only paying 75% of the original price. Simply multiply $39.50 by 75%(expresses as 0.75) to determine the sale price. 39.50(.75)=29.62 The closest value to that is $29.50, so D is the answer.
