Extracted text: Questions 1-5 are in reference to the following scenario: Each evening, a team of employees at a company assembles vegetable, roast beef, and chicken sandwiches to be placed in vending machines the following morning. Only 960 minutes of assembly time are available each evening. Each vegetable sandwich takes .4 minutes to assemble, each roast beef sandwich takes .3 minutes to assemble, and each chicken sandwich takes .5 minutes to assemble. The vending machines have room for at most 2000 sandwiches. To insure variety, the company wants to provide at least 200 of each type of sandwich. The revenue per vegetable sandwich is $3.00, per roast beef sandwich is $4.00, and per chicken sandwich is $3.50. The company wants to know how many of each type of sandwich to assemble each evening to maximize total revenue. (The company is assured of selling all the sandwiches it provides.) The minimum sandwich constraint may be stated as: O Xv s 200 and Xr s 200 and Xc s 200 O Xv + Xr + Xc = 200 O Xv + Xr + Xc 2 200 O Xv 2 200 and Xr 2 200 and Xc 2 200
