the manager of a take out pizza parlor needs to hire pizza makers and cahiers for the evening shift. the total number of employees of both kinds can be at most 16, and the ratio of cashiers to pizza makers must be at least 3 to 5. Also, each pizza maker can answer 12 phone calls per hour, while each cahier can answer 4 calls per hour, and the pizza parlor must be able handle at least 72 calls during peak hour.... each pizza maker gets $10 per hour. Each cashier gets $6 per hour. How many pizza makers and how many cashiers should the manager hire in order to minimize her cost?
