A factory manufacturesa chairs and tables, each requiring the use of three operations: Cutting, assembly, and finishing. The first operation can be used at most 40 hours: the second at most 42 hours: and the third at most 25 hours. A chair requires 1 hour of cutting, 2 hours of assembly, and 1 hour of finishing: a table needs 2 hours of cutting: 1 hour of assembly: and 1 hour of finishing. If the profit is $20 per unit for a chair and $30 a unit for a table, how many units of each should be manufactured to maximize profit?
