Math Problem Statement
A furniture manufacturer produces chairs and sofas. Chairs require 20 feet of wood, 1 lb. of foam rubber, and 2 square yards of material. Sofas require 100 feet of wood, 50 lbs. of foam rubber, and 20 square yards of material. The manufacturer has 1900 feet of wood, 500 lbs. of foam rubber, and 240 square yards of material in stock. If chairs can be sold for $20 each and sofas for $300 each, how many of each should be produced to maximize income?

Formulas
Maximize Z = 20x + 300y
20x + 100y ≤ 1900 (wood constraint)
x + 50y ≤ 500 (foam rubber constraint)
2x + 20y ≤ 240 (material constraint)
x ≥ 0, y ≥ 0 (non-negativity constraints)
