PSAT Math Multiple-Choice Question 367: Answer and Explanation

Question: 367

A company sells dolls for $20 each. It decides to offer a discount of 20 percent for a month to see how many new customers it can attract. How much will each doll sell for during the month of the discount?

• A. $12
• B. $14
• C. $16
• D. $18

Correct Answer: C

(C) is correct.
