In the design of an automobile engine part, an engineer has a choice of either steel casting or an aluminum alloy casting. Either machine provides the same service. However, the steel casting weighs 8 ounces, compared with 5 ounces for the aluminum casting. Every pound of extra weight in the automobile has been assigned a penalty of $6 to account for increased fuel consumption during the life cycle of the car. The steel casting costs $3.20 per pound, while the aluminum allow can be cast for $7.40 per pound. Machining cost per casting are $5.00 for steel and $4.20 for aluminum. Which material should the engineer select, and what is the difference in unit costs? 1 pound = 16 ounce
