In a small printing business, P = 2N^0.6V ^0.4, where N is the number of workers, V is the value of the equipment (in equipment units), and P is production, in thousands of pages per day.
(a) If this company has a labor force of 300 workers and 200 units of equipment, what is production?
(b) If the labor force is doubled (to 600 workers), how does production change?
(c) If the company purchases enough equipment to double the value of its equipment (to 400 units), how does production change?
(d) If both  N and V are doubled from the values given in part (a), how does production change?
