A company produces three products A1, A2, A3 by mixing three ingredients B1, B2, B3. The selling price for A1, A2 and A3 is $13, 14 and 16 $/kg, respec- tively, and at most 75,80 and 90 kg of each can be sold daily. The cost of B1,B2,B3 is 7, 2 and 4 $/kg and the daily supply is at most 40, 95, and 65 kg, respectively. In addition, there are the following technological constraints: A1 must contain exactly 10% of B1, at least 30% of B2, and at most 50% of B3; A2 must contain exactly 30% of B2, at least 20% of B3, and at most 10% of B1. A3 must contain exactly 15% of B3, at least 15% of B2, and at most 15% of B1; *Determine the mixing scheme which will maximize the profit 3. The attempt at a solution I think I need to maximize 13a1 + 14a2 + 16a - 7b1 -2b2 -4b3 but im not sure how the constraints for the A(1-3) products would go.
