Answer:
To calculate how much Mr. Wang ends up paying for the $15 box of trail mix at Whole Foods with a 10% coupon and a 6% tax, follow these steps:
Calculate the discount amount using the 10% coupon:
Discount = (Coupon Percentage / 100) * Price
Discount = (10% / 100) * $15
Discount = 0.10 * $15
Discount = $1.50
Subtract the discount from the original price to get the discounted price:
Discounted Price = Price - Discount
Discounted Price = $15 - $1.50
Discounted Price = $13.50
Calculate the tax amount using the 6% tax rate:
Tax Amount = (Tax Rate / 100) * Discounted Price
Tax Amount = (6% / 100) * $13.50
Tax Amount = 0.06 * $13.50
Tax Amount = $0.81
Add the tax amount to the discounted price to find the total amount paid:
Total Amount Paid = Discounted Price + Tax Amount
Total Amount Paid = $13.50 + $0.81
Total Amount Paid = $14.31
Mr. Wang ends up paying $14.31 for the $15 box of trail mix after applying the 10% coupon and including the 6% tax.
