Traci wants to buy rings that cost $50 each. jeweler is offering a deal in which you buy 1 ring and get the 2nd for 25% off and 50% off for the 3rd she buys 3 rings how much money does she save for all the rings

Well you pay 50$ for the first one, for the second one your paying 12.50 less and for the third one your paying 25 less, if you add them together you get 112.5, it originally would have costed 150, so you would subtract 150 - 112.5, which equals 37.5 so she saved 37.5 dollars on the rings(Here is a quick simple short way to do it.. she payed 12.50 less and 25 less that added together is 37.5)
