Given x units of capital and y units of labor, a company produces P(x, y) = 10x^(1/2)y^(1/3) units of its product. Each unit of capital costs $2000, and each unit of labor costs $4000. Use Lagrange multipliers to find the values of x and y which maximize the company's production if the company spends $20,000 total on capital and labor. You may assume the maximum occurs at a point where the Lagrange multipliers condition is satisfied.
