Luisa wants to purchase 2 DVDs. At Stay and Play DVDs are on sale-buy 1 get 1 free. At Barney's the DVDs are 25% off. Which is a better deal?
+2666 Assume the DVD costs \(d\), For the first option, you would only pay the cost of one \(d\). For the second option, you would pay the cost of \(d + 0.75d\), because the first one costs \(d\), and the second one costs \(0.75d\). Thus, the first option is the better deal.
