7. Leann's Telecommunication rm uses the production function given by wlw y(K, L) = 300(KL) where K is the number of internet servers and L is the number of labor hours. a) Does this production function exhibit increasing, constant or decreasing returns to scale? b) Holding the number of internet servers constant at 8, is the marginal product of labor increasing, constant or decreasing as more labor is used? c) Find the expression of the marginal rate of technical substitution (MRTS) for this production function. If the number of internet servers is still 8, how many labor is needed to produce 30,000 units of output? What is the value of MRTS at this combination of labor and capital
