Bob is having a party and wants to order some cakes there will be 57 guests and he wants to make sure everyone gets a slice of cake he wants to pay as little as possible for the cakes and for them to be the same size how much will he pay for the cakes

The standard half-sheet cake has 24 servings. Two cakes equals 48 slices. Three cakes equal 72 slices. If Bob buys two half-sheet cakes and one standard 9-inch round cake, which has 12 servings, Bob would have 60 servings of cake. That would be the route for actual cake. If he wants the cakes all the same size without a lot of cost, Bob should get five dozen cupcakes.
