Linear Programming
Describe and sketch the regions in the first quadrant of the
x1−x2 plane determined by the
inequalities. Remember that the graphical method of solving a
linear programming problem is used when there are only two decision
variables. If the problem has three or more variables, the
graphical method is not suitable. Then maximize or minimize the
given objective function f subject to the given
constraints.

Production: A furniture company produces inexpensive tables and chairs. The production process for each is similar in that both require a certain number of hours of carpentry work and a certain number of labour hours in the painting department. Each table takes 4 hours of carpentry and 2 hours in the painting department. Each
chair requires 3 hours of carpentry and 1 hour in the painting department. During the current production period, 240 hours of carpentry time are available and 100 hours in painting is available. Each table sold yields a profit of R7; each chair produced is sold for a R5 profit. Find the best combination of tables and chairs to manufacture in order to reach the maximum profit.
