A DVD player was originally priced at $75. During a sale, a salesperson named Ezra sold the DVD player for 20% off. If he earns a 15% commission on the sale price, how much did Ezra make from the sale?
First find the discount price. Write 20% as the decimal 0.20 before using it in the equation.
discount price = original price − discount
= 75 − 0.20 × 75
= 75 − 15
= 60
The discount price was $60.
Now find the commission. Write 15% as the decimal 0.15 before using it in the equation.
commission = commission percentage × sales
= 0.15 × 60
= 9
The commission was $9.
