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 one appropriate constraint for this scenario?

Question

Quizplus · Accepted Answer

The correct constraint for the scenario is the total cost of cat and dog food combined must be less than or equal to $40. Since cat food costs $0.50 per can (C) and dog food costs $1 per can (D), the equation .5C + 1D ≤ 40 represents the maximum amount Lisa can spend on cat and dog food within her budget.
