Question: 46

2. A coat was on sale for 50% off. Katie bought the coat, using a "$10 off the current price" coupon. If she paid $35 for the coat, what was its original price?

A. $45
B. $70
C. $80
D. $90
E. $95

Correct Answer: D


D. The easiest approach to this problem is to start at the end: Katie used her $10 coupon and paid $35, so the price was $45 without the coupon. Because this price was 50% off the original price, it originally cost twice as much, or $90.
