So I got some help coming up with a linear program problem for my class (I am a student teacher) and the information is below but I am trying to figure out the solution and worried I have it incorrect. So how would I solve the solution?

A man can make either small or large tables. He can sell small tables for $20 and large tables for $30 and wants to maximize revenue.

Each small table takes 2 hours to make and each large table takes 3 hours. He has a total of 40 hours.

Each small table take 10 square feet of wood. Each large table takes 20 square feet. He has a total of 1500 square feet of wood

Each small table takes 12 screws. Each large one take 14. He has 2200 screws.

This is a simple example where we want to maximize 20x + 30y subject to three constraints.

Please explain the meaning of your solution.
