Question

A chair's regular price is $349. It is on clearance for 30% off, and a customer uses a 15% off coupon after that. What is the final cost of the chair before sales tax?

Answer 1

The price paid by the costumer was 207.655 $

Explanation:

The original price of the chair is 349 we need to compute the price after the first discount of 30%, since it was a discount the new price will be 100% - 30% = 70% of the original price, so we need to find that value by using the following equation:

Price after first discount = Original price *(70/100)

Price after first discount = 349 * 0.7 = 244.3 $

The customer used a coupon on top of that of 15%, since it was also a discount we need to compute 85% of the new price (244.3) by using the following equation:

Price after second discount = Price after first discount * (85/100)

Price after second discount = 244.3 * 0.85 = 207.655 $

The price paid by the costumer was 207.655 $

Answer 2

$207.66

Explanation:

Regular price = $349

clearance price = 30% of $349

= 0.03 * 349 = $104.7

therefore new price = $349 - $104.7 = $244.3 ( 70% of original price )

A customer using a 15% off coupon then the price would be

= ( 100% - 15%) ( 70% of $349 )

= 85% ( 70% of original price )

= 0.85 * $244.3 = $207.66 ( final cost of chair before sales tax )

sales tax is a tax been paid by the buyer on purchased item and the buyer purchasing the item after applying his coupon means that he would pay sales tax on the final price at which he bought the item and not the original price of the item.
