responses.

Carefully define the term "model" and explain how models are used in managerial
economics.
A furniture manufacturer produces three types of chairs. Model A requires 1.2 hours of
labor and .25 hour of machine time. Model B requires 1 hour of labor and .2 hour of
machine time. Model C requires .8 hours of labor and .15 hours of machine time. There
are 600 labor hours and 200 machine hours available per period. The manufacturer
seeks to maximize profit and has determined that profit contributions of each unit of A,
B, and C are $20, $15, and $12, respectively. Formulate as a linear program.
A firm is mulling over its optimal mix of print advertising. Magazine ads (M) cost
$2,500 each, reach an estimated 20,000 consumers, and generate about $7,500 revenue
per ad. Newspaper ads (N) cost $1,500 each, reach an estimated 15,000 consumers, and
generate about $6,000 revenue per ad. The advertising budget is $75,000 and
management wishes to reach at least 600,000 consumers in total. In addition, the firm
wants to have at least twice as many magazine ads as newspaper ads. Formulate the
firm's linear programming problem.
