Answer 1

To solve these problems, calculate the difference between the original and sale prices to determine the discount percentage, then add the discounted price to any other costs and calculate tax based on the total to find the final amount paid.

Step-by-step explanation:

The question involves calculating the percent discount on the headphones and determining the total amount paid for the headphones including sales tax.To find the percent discount:Determine the original price and the sale price of the headphones.Calculate the difference between the original price and the sale price.Divide the difference by the original price.Multiply by 100 to convert to a percent.

To determine the total amount paid including tax:Add the discounted price of the headphones and any other items purchased to get the total pre-tax cost.Convert the sales tax percentage to a decimal by dividing by 100.Multiply the total pre-tax cost by this decimal to find the sales tax.Add the sales tax to the total pre-tax cost to get the final total paid.
