Assignment

John Pebbles requested Albert Rock to transport a group of young people to a concert. The agreed cost of the trip was $5000. John made a down payment of $100. However, the group felt that the price was too much, and decided to cancel the trip. Albert was not informed about the change of plans so he presented his vehicle at the appointed time to take the group to the concert. John Pebbles then told Albert that he was very sorry that the group had changed its plans. Albert demanded that John pay him immediately or face the courts. John refused to pay on the ground that he received no service from Albert.

Based on the information in the case, justify why the arrangement between John and Albert can be considered a valid contract. (4 Marks)
