Mackk Engine produces diesel trucks. New government emission standards have dictated that the average pollution emissions of all trucks produced in the next 3 years cannot exceed 10 grams per truck. Mackk produces 2 types of trucks. Each type 1 truck sells for $20,000, costs $15,000 to manufacture, and emits 15 grams of pollution. Each type 2 truck sells for $17,000, costs $14,000 to manufacture, and emits 5 grams of pollution. Production capacity limits total truck production during each year to at most 320 trucks. The maximum numbers of each truck type that can be sold during each of the next 3 years are listed in the file P04_113.xlsx. Demand can be met from previous production or the current year’s production. It costs $2000 to hold 1 truck (of any type) in inventory for 1 year. Determine how Mackk can maximize its profit during the next 3 years.
