An item is regularly priced at $25. Lamar bought it on sale for 15% off the regular price.
To calculate the discount amount, multiply the regular price by the 15% discount rate:
Discount = $25 * 0.15 = $3.75
Then subtract the discount from the regular price to find the sale price:
Sale price = $25 - $3.75 = $21.25
Lamar bought the item for $21.25.
