Caroline wants to buy a pair of shoes that has an original price of $80.00. She has a coupon for a 40% discount off of the original price. Her state charges an 8% sales tax on the discounted price. What is the final cost for Carolines shoes?

$34.56

Step-by-step explanation:

Let's start by findig the discount price.

40% off? Nice. 40% of 80 is 32 so the discount price would be $32.00.

Then there is the sales tax. 8% on the discounted price. So 108% of 32 is the total answer.

If you do it correctly, the price would be $34.56.

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21
