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. Lisa would like to buy enough food to last through her three-day weekend. What is an appropriate objective function for this scenario?

Question

Quizplus · Accepted Answer

The objective function should minimize the cost of the food. Since dog food costs twice as much as cat food, the objective function should reflect that by multiplying the number of cans of dog food by 1 and the number of cans of cat food by 0.5. Therefore, the appropriate objective function is Min Z = 1D + 0.5C.
