A tailor makes wool tweed sports coats and wool slacks. He has 150 square yards of wool each month to make coats and slacks. And 200 hours of labor each month. A coat requires 3 yards of wool and 10 hours to make while a pair of pants requires 5 square yards of wool and 4 hours to make. He earns P50.00 from each coat and P40.00 from each pair of slacks. He wants to know how many coats and slacks to produce that would give him the maximum profit.
