A $20 scarf can be discounted as much as 50 percent, and 50 percent of 20 is $20 * 50/100, so the minimum sale price of a scarf is $20 − $10 = $10. The least discount is 25 percent, and 25 percent of 20 is $20*25/100, so the maximum sale price of a scarf is $20 − $5 = $15. Therefore, the range of possible sale prices for scarves is $10 to $15. Now, eliminate choices that fall outside of that range. Choice (A) is less than $10, and (E) is greater than $15, so eliminate both of them.
The correct answer is (B), (C), and (D).
