Question

A discount store bought 12 dozen radios, each to be sold at $15 above cost. The store sold x of the radios at that price. Each of the remaining radios was sold at $4 below cost. If the store paid $11 for each radio, what was the total income from the sale?

Answer 1

cost = 144*11
revenue = x(11+15) + (144-x)(11-4)
