In January 2009, Amy started a business as an independent website designer.
To give her a start in her career, her brother Ben, who ran a retail business, said he would give her £1,000 if she updated his business website. At the same time, her friend Che asked her to do work for his business, also for a set fee of £1,000.
However, by the time Amy had completed the two projects her design business had become a huge success and she had lots of other clients. When Ben and Che discovered how successful Amy’s business had become they both felt that they should not be asked to pay for the work they had commissioned.
Ben said he would not pay anything as he had only offered the work to help his sister out. Che said he would not pay anything either, on the basis that he had only given her work to do on the basis of their friendship.
Required:
