*7. An industrial recycling center

*7. An industrial recycling center uses two scrap aluminum metals, A and B, to produce a
special alloy. Scrap A contains 6% aluminum, 3% silicon, and 4% carbon. Scrap B has
3% aluminum, 6% silicon, and 3% carbon.The costs per ton for scraps A and Bare $100
and $80, respectively. TIle specifications of the special alloy require that (1) the aluminum
content must be at least 3% and at most 6%, (2) the silicon content must lie between 3%

2.3 Selected lP Applications 27
and 5%, and (3) the carbon content must be between 3% and 7%. Determine the optimum
mix of the scraps that should be used in producing 1000 tons of the alloy.
