Monkey chunks cereal is normally $3.25 per box but today it is on sale for 25% off. what is the new price?

So, you are attempting to find 25% off of the price so there are two ways to do it.

1. Multiply the price times 25%, which becomes .25
3.25 x .25 = .81
Subtract that amount from the original price
3.25 - .81 = $2.44

2. Get the amount that will be left after 25%
100 - 25 = 75
Multiply the old price times .75
3.25 x .75 = 2.4375, so $2.44
