Use graphical means to solve the following linear programming problem: A contractor builds two types of homes. The first type requires one lot, $20,000 of capital, and 200 labor-days to build and is sold for a profit of $15,000. The second type requires one lot, $40,000 of capital, and 800 labor-days to build and is sold for a profit of $40,000. The contractor owns 100 lots and has available $2,400,000 in capital and 40,000 labor-days. How many homes of each type should she build to realize the greatest profit? Y Available Profit Lots Capital Labor-Days 200 190 180 170 160 150 140 130 120 110 100 90 80 70 60 50 40 30 20 10 0 1
