$15.75
Steps to Solve
- Calculate the discount amount
To find the discount amount, we must calculate 25% of the original price, which is $20. To do this, multiply the original price by the discount percentage (as a decimal):
$Discount = OriginalPrice * DiscountPercentage$
$Discount = 20 * 0.25 = 5$
- Subtract the discount from the original price
To find the discounted price, subtract the discount amount from the original price:
$DiscountedPrice = OriginalPrice - Discount$
$DiscountedPrice = 20 - 5 = 15$
- Calculate the sales tax amount
To find the sales tax amount, multiply the discounted price by the sales tax percentage (as a decimal):
$SalesTax = DiscountedPrice * SalesTaxPercentage$
$SalesTax = 15 * 0.05 = 0.75$
- Add the sales tax to the discounted price
To find the final price, add the sales tax to the discounted price:
$FinalPrice = DiscountedPrice + SalesTax$
$FinalPrice = 15 + 0.75 = 15.75$
$15.75
