You are the marketing manager of a firm that produces titanium and sells this metal to
two distinct kinds of customers: aircraft producers and golf club manufacturers.
Demand for titanium by these two market segments is quite different, as described by
the respective price equations: PA= 10 '“ QA/600 and PG= 12 '“ QG/100, where annual
quantities [QAand QG] are in thousands of pounds and prices [PAand PG] are in dollars.
Your firm estimates the marginal cost of titanium production at $4 per pound.
(a) For each segment, determine the firm's profit-maximizing price and output. Is the
firm practicing price discrimination?
(b) Because of titanium shortages, the firm's total production capacity drops to only 1.5
million pounds per year. Determine the firm's optimal quantities and prices in this case.

The manager of an appliance store wishes to obtain survey responses from a sample of
at least 900 households regarding their future-purchase plans. The cost of mail surveys
(M) is $1 each, while the cost of telephone surveys (T) is $3 per call. Response rates are
60% for telephone calls and 30% for mail questionnaires. To assure sufficient response
accuracy, the manager insists on gathering at least three times as many actual telephone
responses as mail responses. The manager's objective is to minimize the cost of the
survey (C), while meeting the stipulated goals. Formulate and solve the firm's linear
programming problem.
