The daily output at a plant manufacturing clocks is approximated by the function f(L,K) = 25K3/10 VL clocks where L 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 $24,000 and the average wage of an employee is $11.50 per hour, what combination of worker-hours (to the nearest hundred) and capital expenditures (to the nearest thousand) will yield maximum daily production? a) 600 worker-hours and $20,000 in capital expenditures b) 1500 worker-hours and $6,000 in capital expenditures c) 200 worker-hours and $22,000 in capital expenditures d) 700 worker-hours and $14,000 in capital expenditures e) 800 worker-hours and $14,000 in capital expenditures f) 500 worker-hours and $18,000 in capital expenditures
