A company produces three products, A, B, and C, and can sell these products in unlimited quantities at the following unit prices: A, $10; B, $56; C, $100.

Producing a unit of A requires 1 hour of labor; a unit of B, 2 hours of labor plus 2 units of A; and a unit of C, 3 hours of labor plus 1 unit of B. Any A that is used to produce B cannot be sold. Similarly, any B that is used to produce C cannot be sold. A total of 40 hours of labor is available. Determine how to maximize the company’s revenue.
