For a telephone survey, a marketing research group needs to contact at least 150 wives, 120 husbands, 100 single adult males, and 110 single adult females. It costs $2 to make a daytime call and (because of higher labor costs) $5 to make an evening call. Table 52 lists the results Because of limited staff, at most half of all phone calls can be evening calls. Formulate an LP to minimize the cost of completing the survey.
table 52
Person Responding | Percent of Daytime Calls | Percent of Evening Calls |
Wife | 30 | 30 |
Husband | 10 | 30 |
Single male | 10 | 15 |
Single female | 10 | 20 |
None | 40 | 5 |
