In the design of a jet engine part, the designer has a choice of specifying 10 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. Every kilogram of excess weight is associated with a penalty of P 1,300 due to increased fuel consumption. Which material should be specified and what is the economic advantage of the selection per unit? Clue: Total Cost of using aluminum casting and steel casting and also how much will be saved. *
