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 of painting. Each chair requires 3 hours of carpentry and 1 hour of painting. 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 $70.00; each chair produced is sold for a $50.00 profit. Find the best combination of tables and chairs to manufacture in order to reach the maximum profit.

What are the constraint inequalities for this problem?
