Question

Debbie found a suitcase that was originally 129 but now is on sale for 30% off. If sales tax is 8.75%, what is her final cost?

Answer 1

$98.20

Explanation:

"30% off" refers to the discount (amount by which the original price is reduced); 100% - 30%, or 70%, refers to the sale price. It's the latter that we want. Multiply $129 by 0.70 to obtain the sales price, obtaining $90.30.

The final cost to Debbie is this sales price plus the 8.75% sales tax. Multiply this $90.30 by 1.0875 to obtain the sales price: $98.20.

Answer 2

Explanation:

To find the answer we first multiply 129 by 0.7 since the price descresed 30 percent. each percent is equal to 0.01.

129 * 0.7 = 90.3

Then we multiply 90.3 by 1.0875 since that is the sales tax

90.3 * 1.0875 = 98.2

so the cost is 98.2
