A foundry smelts steel, aluminum, and cast-iron scraps to produce two types of metal ingots, I and II, with specific limits on the aluminum, graphite and silicon contents. Aluminum and silicon briquettes may be used in the smelting process to meet the desired specifications. Table 1 and Table 2 set the specifications of the problem: Contents (%) Input item Cost/ton ($) Available tons/day Aluminum Graphite Silicon Steel scrap 10 5 4 100 1000 Aluminum scrap 95 1 2 150 500 0 15 8 15 2500 Cast iron scrap Aluminum briquette Silicon briquette 100 0 0 900 Any amount Any amount 0 0 100 380 Table 1.
