Question

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?

Answer 1

You bought the canisters for $2.50 ($60 / 24)

What is $4 - $2.50? That is the markup.
