Answer 1

A. If the item is 15% off, that you will find out what 15% of the original price is and take that amount off.

0.15 x 800=120.
$800-$120=$680

B. The price is decreased by 15%, therefore the discount is similar.

C. The sales tax is 8% of the $680,
0.08 x 680=$54.40

D. This amount of sales tax is added to the sale price, so it would be considered an increase to the price.
