C. Does this production function have increasing, decreasing, or constant returns to scale?
D. Which input bundle represents efficient production of 100 units of output if the rental paid to capital is $25 and the wage paid to labor is $50? Round any decimals to the nearest hundredth.
E. Derive the firm's cost function using the rental and wage listed in Part D.
F. Does this firm exhibit economies or diseconomies of scale?
G. What is the firm's efficient scale of production?
