Crazy Bob fixes fender benders. At his auto body shop, the production function showing the number of cars Crazy Bob repaired each year is Q = K^0.5L^0.5, where K is the number of welding machines and L is the number of employees. Currently K = 9.

1.What is the equation for Crazy Bob's short-run production function expressed as Q and a function of L only.

2.What is the totalnumber of cars that Crazy Bob can repair when L = 4?

3.What is the MP_Lfor the 3rd worker (rounding is fine)?

4.What is the AP_Lfor the 4th worker?
