Question: Suppose a manufacturer's production function is given by: 16q = 65 – 4(1- 4)² – 2(k – 5)² And the cost to the manufacturer is $8 per unit of labor and $16 per unit of capital, so that the total cost (in dollars) is 81 + 16k. The selling price of the product is $64. i. Express the profit as a function of I and k. Give your answer in expanded form. ii. Find all critical points of the function obtained in part (i). Apply the second-order derivative test at each critical point. If the profit is a relative maximum at a critical point, compute the corresponding relative maximum profit. ii. The profit may be considered as a function of I, k, and q, subject to the constraint:

How to do question 3

Question: Suppose a manufacturer's production function is given
by:
16q = 65 – 4(1 – 4)² – 2(k – 5)2
And the cost to the manufacturer is $8 per unit of labor and $16
per unit of capital, so that the total cost (in dollars) is 81 + 16k.
The selling price of the product is $64.
i. Express the profit as a function of I and k. Give your answer
in expanded form.
ii. Find all critical points of the function obtained in part (i).
Apply the second-order derivative test at each critical point.
If the profit is a relative maximum at a critical point, compute
the corresponding relative maximum profit.
iii. The profit may be considered as a function of I, k, and q,
subject to the constraint:
16q = 65 – 4(1 – 4)? – 2(k – 5)2
Use the method of Lagrange multipliers to find all critical
points of the profit function, subject to the constraint.
