To find the sales price of the DVD, you would multiply the price and sale percent to get the sale price.
You would need to turn 20% into a decimal to multiply it with 9, so you would move the decimal place two times to the left: From 20. to→ .20
In this case: 9 × .20 = 1.8
Then you would subract the sub price by the sales price
9 - 1.8 = 7.2
The sales price of the DVD would be $7.20
I believe that the answer would be 2 but im not 100% positive
