The Cobb-Douglas production function for a particular product is N(x, y)=40 x^0.8 y^0.2, where x is the number of units of labor and y is the number of units of capital required to produce N(x, y) units of the product. Each unit of labor costs $80 and each unit of capital costs $120.

If $1, 200,000 is budgeted for production of the product, determine how that amount should be allocated to maximize production.

Production will be maximized when using units of labor and ___units of capital.
