**Cobb-Douglas Production Function Example**

Suppose a Cobb-Douglas Production function is given by the following:

\[ P(L, K) = 20L^{0.6}K^{0.4} \]

where \( L \) is units of labor, \( K \) is units of capital, and \( P(L, K) \) is the total units that can be produced with this labor/capital combination. Suppose each unit of labor costs $700 and each unit of capital costs $1,400. Further suppose a total of $175,000 is available to be invested in labor and capital (combined).

**A) How many units of labor and capital should be "purchased" to maximize production subject to your budgetary constraint?**

- Units of labor, \( L \) = [_________]

- Units of capital, \( K \) = [_________]

**B) What is the maximum number of units of production under the given budgetary conditions? (Round your answer to the nearest whole unit.)**

- Max production = [_________] units

Expert Solution
Step 1: Analysis and Introduction

Given Information:

Cobb Douglas Production Function P open parentheses L comma K close parentheses equals 20 L to the power of 0.6 end exponent K to the power of 0.4 end exponent.

Here, L is the unit of Labor and K is the unit of capital.

Each unit of labor costs $700 and each unit of capital costs $1400.

Total cost is $175,000.

To find:

The unit of labor and the unit of capital which gives the maximum production.

Solution Process:

Step 1: Use Lagrange multiplier, form the function L(x,y,λ) and partially differentiate on each variable.

Step 2: Equate each derivative to zero and find the critical point of L(x,y,λ).

Step 3: Find the function value at the critical point and classify them into maximum and minimum.
