You want to buy the newest gaming system, which costs $500. In addition, you want to be able to buy the accessories that go with it (e.g., controllers, games, headsets, etc.). You already have $150 saved up from your birthday but decide to ask your neighbors if you could wash their dogs to earn more money. You charge $10 per dog.
