How do you figure out the sale price from its original price in math class here is an example The Camping Store is having a sale The discount is 15 percent on all items what was the sale price?

well there is two ways of answering this...

1st way

take the price of the item (lets say $20) and multiply by the decimal equivalent of your percent off.

20*.15=3

That figured up your discount so to get they price you would pay you simply subtract your discount from the original price to get the sale price.

20-3=17

2nd way

The other way is to subtract your percent off from 100(since 100% would be full price) to find the percent you would pay.

100-15=85

then just multiply by the decimal equivalent of your percent that you would pay by the original price to get the sale price.

20*.85=17

both ways will get you the same result if the values are inserted correctly
