I want to buy three dogs, four cats, and three pigs. I want the combined age of the three dogs, four cats, and three pigs to be as low as possible. My budget is $79. I’m going to list the price and age of a bunch of dogs, cats, and pigs and I want you tell me which combination of three dogs, four cats, and three pigs has the lowest possible combined age without exceeding my budget of $79.
