Calista’s Doggie Goods produces two models of its doggie tents, the Doggie Trekker and the Doggie Diva. The Doggie Trekker tent requires 3 hours of assembly time, and the Doggie Diva tent requires 5 hours; only 150 hours of assembly time are available next week. Also, Calista’s Doggie Goods currently has only 20 of the heated bottom units used in the Doggie Diva tent, thus, no more than 20 units of the Doggie Diva may be assembled. Each unit of the Doggie Trekker requires 8 yards of Gore-Tex coated fabric and each Doggie Diva unit of the Portable requires 5 yards of Gore-Tex coated fabric. Only 300 yards of the Gore-Tex fabric are currently available. Mika, the Marketing Manager, knows from past sales that owners of small dogs like the Doggie Diva tents and that the company will sell at least two times more Doggie Diva tents as the Doggie Trekker tents. The Doggie Trekker generates a profit contribution of $100 per tent, and the Doggie Diva generates a profit contribution of $80 per tent. Formulate the LP model.
