Question

30 point for this plz help!! And explain how you got you answer

The original price of a DVD is $9. The sale price is 20% off the original price. What is the sale price of the DVD?

Answer 1

The sale price is $7.20. Here are the steps. To find how much 20% is of $9, you must multiply .20 × $9 After that, you end up with $1.80 Take the $1.80 and remove that from the $9 To get a sale price of $7.20

Answer 2

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
