for B formulate as a linear programming problem

3. A craftsman named William Barnes builds two kinds of bird houses, one for wrens and a second for bluebirds. Each wren birdhouse takes 4 hours of labor and 4 units of lumber. Each bluebird house requires 2 hours of labor and 12 units of lumber. The craftsman plans to work exactly 60 hours and has 120 units of lumber available. Currently, the craftsman has orders for 5 wren houses and 10 bluebird houses. Wren houses yield a profit of $6 each, and bluebird houses yield a profit of $12. a) Summarize the information in table similar to that on pg.701 in your text. b) Formulate the problem as a linear programming
