LESSON 3
Optimization Techniques
Activity 3 Case 2
1. Assume that the firm's cost function is given by TC = 30 + 5Q + Q 2 where, Q is the level of output produced and sold,
Assume further that the demand for the output of the firm is a function of price P given by the relationship
Q = 20 - P
A. Define the total profit function as the difference between total revenue and total cost, expressed in terms of Q the total profit function for the firm.
B. Determine the output level where total profits are maximized.
C. Calculate total profits and selling price at the profit-maximizing output level.
2. Mags, Inc. has determined through regression analysis that its sales (TR) are a function of the amount of advertising (measured in units) in two different media. This is given by the following relationship (X = newspapers, Y = magazines):
TR = 300X + 100Y - 10X2 - 20Y2 + 20XY
A. Determine the level of newspaper and magazine advertising that maximizes sales subject to this budget constraint.
B. Calculate the firm's sales at this constrained optimum level.
