The daily output at a plant manufacturing radios is approximated by the function f(L, K) 10K3/5/I radios = where I is the size of the labor force measured in hundreds of worker-hours and K is the daily capital investment in thousands of dollars. If the plant manager has a daily budget of $10,000 and the average wage of an employee is $7.00 per hour, what combination of worker-hours (to the nearest hundred) and capital expenditures (to the nearest thousand) will yield maximum daily production?
