1. An $800 dress is 27% off. What is the selling price. 2. How much will you pay, including 8.875% sales tax?
3. It costs $9 to make a pair of sneakers. It is then marked up 900%. What is the selling price?
4. How much will you pay including 8.875% sales tax?

Step-by-step explanation:

1) 800*27=21600

21600÷100=216

800-216=584

So 584 $ is the selling price.

2) 584*8.875=5183

5183÷100=51.83

So 51.83 $ is the 8.875 sales tax

So 584+51.83=635.83$

3). 9*900=8100

8100÷100=81

So the price is 81$

4)81*8.875=718.875

718.875÷100=7.18875 round it 7.2

Now add : 81+7.2=88.2
