6. You buy a pair of shoes that cost $120. You use your 20% off coupon and pay an 9% tax. What is your total bill?

$104.64

Step-by-step explanation:

Because coupons come before tax, we have to take away 20%, then add 9%

Step 1 : Find 20%

In order to find the percent of anything, all you have to do is multiply the percent (as a decimal) by your price

In this case, it's :  120 × 0.20

Using this expression, we find that 20% of $120 = $24

Step 2 : take away 20%

Coupons take away money from a full price, so we will take away $24 from $120, leaving us with $96

Step 3 : Find 9%

Now we multiply 0.09 (9%) by our new price (96)

96 × 0.09 = $8.64

Step 4 : Add 9%

Lastly, we use our coupon-added price (96) and add our tax (8.64)

96 + 8.64 = $104.64

wait nvm i know the correct answer now its 100%   81 square feet
