Bellevue BUSI BA 623 – A baker uses organic flour from a local farmer

| March 14, 2016

UESTION 1

A baker uses organic flour from a local farmer in all of his baked goods. For each batch of bread (x1), he uses 4 pounds of flour. For a batch of cookies (x2), he uses 3 pounds, and for a batch of muffins (x3) he uses 2 pounds. The local farmer can supply him with no more than 24 pounds per week. The constraint that represents this condition is:

x1 8, x2 8, x38

x1+ x2 + x324

x1+ x2 + x3 24

4×1+ 3×2 + 2×3 24

QUESTION 11

It’s time to buy pet food again and Lisa heads to the grocery store with $40 in her purse, leaving her seven hungry cats and four hungry dogs at home. Dog food costs $1 per can and cat food costs $0.50 per can. Dogs eat two full cans of food each day but cats eat only one can.
