What is the discount amount on a $40 shirt discounted by 10%?

• A. $4
• B. $40
• C. $6
• D. $14

Answer: (A)

Understanding percents of a number. A 10% discount means you take away 10 out of every 100, which is the decimal 0.10. To find the discount on a $40 shirt, multiply 40 by 0.10: 40 × 0.10 = 4. So the discount amount is $4. The sale price would be $36, but the question asks for the discount itself. The other amounts would come from using different percentages (for example, $40 is the full price, not the discount; $6 would be 15% of 40; $14 would be 35% of 40).
