KeenKen the monkey is going shopping! KeenKen currently has units of sugar, but he needs units of sugar. He has units of toothpaste, but he needs units of toothpaste.

If he doesn't have enough sugar, he will have to go to the grocery store to get some. If he doesn't have enough toothpaste, he will have to go to the pharmacy. However, if he needs both, he can get them both at the department store, but that is farther away. Thus, he will only visit the department store if he needs to get both items.

If he doesn't need to get either item, KeenKen will stay home.

Please tell KeenKen what to do!
