In the design of a jet engine part, the designer has a choice of specifying either an aluminum alloy casting or a steel casting. Either material will provide equal service, but the aluminum casting will weigh 1.2 kg as compared with 1.35 kg for the steel casting. The aluminum can be cast for P 80.00 per kg. and the steel one for P 35.00 per kg. The cost of machining per unit is P 150.00 for aluminum and P 170.00 for steel.
