a) Carl and Paul are brothers who pooled their money and bought an antique Cadillac car, with an idea that people might want to hire it out for special events. They spent many months restoring it to its former glory. After hiring out the Cadillac for several months, they had made enough money to buy and restore a second antique car. Carl is now restoring the second car, while Paul manages the bookings for the Cadillac. Most of the money earned in this way is spent on restoration costs and the brothers divide what is left between them. Required: What business organisation are the brothers operating under?
