Since it's on sale and her aunt can discount it, the total discount is 40% off. Take 100 and subtract it from 40. You'll get 60. Since 40% is equal to .40, make 60 a decimal as well. .60. Take .60 and multiply it by 160. You'll get 96. Now for the tax.
Take 7.5 and ADD it to 100, giving you 107.5. Move the decimal over twice making it 1.075. Take 1.075 and multiply it by the 96 we got earlier. That gives you $103.20
The answer is $103.20

Answer:

Claire will pay for the dress $ 103.20

Step-by-step explanation:

The dress Claire wants to buy is $ 160, but the dress is 30% off, and Claire's aunt will give you another 10% off, so Claire will get 40% off. To find out how much this dress will cost, after receiving all discounts, you should do the following calculation:

(160 x 40%) /100% =

6400 / 100 = 64 Discount dollars.

160 dollars - 64 dollars = 96 dollars

The price of the dress after all discounts is $ 96. However, Claire will have to pay 7.5% of this tax price. Thus the final price of the dress is discovered with the following calculation:

(96 x 7,5%) / 100% =

720 / 100% = 7.2 tax dollars

96 +7.2 = 103 dollars and 20 cents.
