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
Let the number be x,
(x*36)/100 = 99
x*36 = 9900
x= 9900/36
x=275
Answer:
x = 2
