Border Patrol Practice Exam

To determine the sale price of the shirt, start by calculating the discount amount. The original price of the shirt is $15, and it is on sale for 20% off. First, convert the percentage to a decimal by dividing 20 by 100, which equals 0.20. Now, multiply the original price by this decimal:

\[

15 \times 0.20 = 3

\]

This calculation shows that the discount is $3. To find the sale price, subtract the discount from the original price:

\[

15 - 3 = 12

\]

As a result, the sale price of the shirt is $12.00, making the first choice the correct answer.
