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 (b/c of higher labor costs) $5 to make an evening call. Because of the limited staff, at most half of all phone calls can be evening calls. Determine how to minimize the cost of completing the survey.
Table lists the results that can be expected. For example, 30% of all daytime calls are answered by a wife and 15%of all evening calls are answered by a single male.
