1. Benefit Cost analysis.Assume a benefit function B = 60*x^.8 and a cost function C = 4 + 7*x^1.5. The maximum difference between B and C are the net benefits. a) Find the value of x that results in the maximum net benefits. b) Would an increase in the fixed cost of 4 affect the value of x? c) Use a Lagrangian model to find the value of the shadow price, or Lagrangian multiplier, if x cannot exceed 5. What does the multiplier signify?

1. Benefit Cost analysis.Assume a benefit function B = 60*x^.8 and a cost function C = 4 + 7*x^1.5. The maximum difference between B and C are the net benefits.

a) Find the value of x that results in the maximum net benefits.

b) Would an increase in the fixed cost of 4 affect the value of x?

c) Use a Lagrangian model to find the value of the shadow price, or Lagrangian multiplier, if x cannot exceed 5. What does the multiplier signify?

Expert Solution
Step 1
