Breezeless Company produces doors and window frames. It generates profit at $2.00 per door and $1.00 per window frame. Manufacture of these products requires two work centers. Work center 1 has 120 labor hours available while work center 2 has 80 hours available. Production of one hundred doors requires 3 hours in work center 1 and 5 hours in work center 2. To produce one hundred window frames, it takes 5 hours in work center 1 and 2 hours in work center 2.
Formulate the preceding problem into linear programming format. Use the seven question and table approach. Work center 2's constraint is:
a. .05D + .02W ≤ 80
b. .05D + .02W ≤ 120
c. 5D + 2W ≤ 80
d. 5D + 2W ≤ 120
e. .05D + .02W ≤ 2
