Question
Mathematics of Linear Programming Solve the following and show your solutions. 1. Solve 3x3 - x2-12x >-4. Then graph the solution set. 2. A shop produces tables and chairs. 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 P9; each chair produced is sold for a P7 profit. Find the best combination of tables and chairs to manufacture in order to reach the maximum profit.
