In the operation of his business, Arty employs labor (N) at a wage of w = 15 per hour, and he employs computers (K), which cost him r = 100 each to maintain for one day. With N hours of labour and K computers, Arty can produce Q = 10K1/2N1/2 units of surveillance output in one day, which he sells for $10 each. Arty currently has 9 computers. [For this production function, MPN = 5K1/2N −1/2 , and MRT S = K N .] (a) (5 pts) In the short run, how much labour will Arty hire per day? How many units of surveillance will he produce?
