Consider the Cobb-Douglas model for a certain manufacturing plant, W = 60H0.610.4 where W is the number of washing machines produced per year, I is the annual investment in capital (in thousands of dollars), and H is the total number of work hours. The annual budget, that pays capital and employees, must be 1 million dollars. Also, employees are paid 10 dollars per hour. Find the number of work hours and annual capital investment that will maximize production. Work hours: hours. Capital Investment: dollars (in thousands) How many washing machines are produced when production is maximized: machines.
