Answer

$7.20 if you round up. Not rounded is $7.198 or just $7.19

Step-by-step explanation

First, get original price which is $9 rounded.

Then, multiple by percent off which would be .20 or .2. Don't get this confused with 2% off which is .02.

After multiplying, you should get the answer of $1.80, this is 20% of $9.00. So if the product was 20% off, you would subtract. This gives you the final answer of $7.20
