The original price is $80 the percent discount is 20% what is the sale price and how did you get it?

Original Price- $80
Discount- 20% which is 0.20

$80 • 0.20 = 16
$80 - 16 = $64

This was how I was taught to do it but I turned 20% into a decimal which is 0.20 and then did 80 times 0.20 which equals 16. From there you minus it by the original price which is $80 and get $64 as your sale price.
Hope that helped
