2. FCC Company manufactures three products A, B, and C to be solved in the market. Product A is produced by process P1, and each unit of product A is obtained in two hours by using 1 unit of raw material R1. Product B is produced by process P2, and each unit of product B is obtained in 1 hour by combining 2 units of product A, 1 unit of raw material R1 and 0.5 units of raw material R2. Product C is produced by process P3, and each unit of product C is obtained in 2 hours by combining 2 units of product B, 0.5 units of raw material R1, 0.5 units of raw material Page 113 R2 and 1 unit of raw material R3. The available time to be allocated to all processes is 960 hours. The unit costs for raw materials R1, R2, and R3 are $50, $20, and $40, respectively. There are 200, 150, and 200 units of raw materials R1, R2, and R3, respectively. The product revenues for the units sold (not for units used in other processes) are $100, $350, and $500, for products A, B, and C, respectively. The maximum numbers of units that can be sold in market are 100, 150, and 200, for products A, B, and C, respectively. However, the number of units of product A sold should be at least 30 percent of all products sold to the market. The production process in this company is illustrated by the figure below.

R2 and 1 unit of raw material R3. The available time to be allocated to all processes is 960
hours. The unit costs for raw materials R1, R2, and R3 are $50, $20, and $40, respectively.
There are 200, 150, and 200 units of raw materials R1, R2, and R3, respectively.
The product revenues for the units sold (not for units used in other processes) are $100, $350,
and $500, for products A, B, and C, respectively. The maximum numbers of units that can be
sold in market are 100, 150, and 200, for products A, B, and C, respectively. However, the
number of units of product A sold should be at least 30 percent of all products sold to the
market.
