SS Airlines sells business and tourist class seats for its charter flights. To charter plan, at least 15 business class tickets and at least 25 tourist class tickets should be sold. The plane doesn't hold more than 60 passengers. For every seat not sold, 300 pounds of cargo can be shipped. SS makes $200 profit upon each business class ticket and $235 one each tourist ticket. For each pound of cargo shipped, SS makes $1.25 in profit. To reduce its profits, how many of each kind of ticket and pounds of cargo should SS sell or ship? What is their maximum profit?
