Shoe Sales

Explanation

We will identify the discount rate and the original price of the shoes and use a formula to find the amount of the discount.  Then we can subtract the discount from the original price to find the sale price of the shoes.

Solution

From the advertisement, we see that the discount rate on the men's shoes is 25% and the original price is 89.80 USD.

• This is the amount of discount formula
  • Amount of discount = discount rate • original price
• Substitute 25% for the discount rate and 89.80 USD for the original price.
  • = 25% • 89.80
• Write 25% as a decimal:  25% = 0.25.
  • 0.25 • 89.80
• Do the multiplication
  • = 22.45

The discount on the men's shoes is 22.45 USD.  The find the sale price, we use subtraction

• This is the sale price formula
  • Sales price = original price - discount
• Substitute 89.80 for the original price and 22.45 for the discount
  • = 89.80 - 22.45
• Do the subtraction
  • = 67.35

The sale price of the men's basketball shoes is 67.35 USD
