Question

A dresser is normally priced at $870. This weekend, however, there is a sale where everything is 15% off. If the sales tax on items is 11.6%, what would be the total cost of the dresser?

a) $683.92
b) $748.80
c) $733.12
d) $715.56

Answer 1

To find the total cost of the dresser, multiply the original price by the discount percentage to find the discount amount. Subtract the discount amount from the original price to get the sale price. Multiply the sale price by the sales tax percentage to find the sales tax amount. Round the sales tax amount and add it to the sale price to get the total cost.

Step-by-step explanation:

1. Find the discount amount by multiplying the original price of the dresser ($870) by the discount percentage (15%) and convert it to a decimal. $870 x 0.15 = $130.50
2. Subtract the discount amount from the original price to get the sale price. $870 - $130.50 = $739.50
3. Next, find the amount of sales tax by multiplying the sale price ($739.50) by the sales tax percentage (11.6%) and convert it to a decimal. $739.50 x 0.116 = $85.773
4. Round the sales tax amount to the nearest cent. $85.773 rounds to $85.77
5. Finally, add the sale price and the sales tax amount to get the total cost of the dresser. $739.50 + $85.77 = $825.27
