Billy and Joel need to divide a car and a dog. Using the Method of Sealed Bids, Billy bids $5000 on the car
and $250 on the dog, while Joel bids $4800 on the car and $280 on the dog. Billy will get the car. Joel will
take the dog and will also get some money from Billy. To make the division fair, how much money will
Billy have to give to Joel?
