For your sports equipment store, you purchase a case containing 24 canisters of tennis balls for $60. You in turn charge $4 for each canister. How much is the price of each case of tennis balls marked up?
I'm assuming that you mean change and therefore if you did first you would work out the change. To do this you would need to do 4x24=96 That means that this question doesn't make sense or I am just doing it totally wrong
