On Monday, Albert inspected Betty’s car at her house in Rongai and offered to pay ksh 3,000,000 for it. Betty wanted Ksh 3,500,000. Later in the day, Betty wrote to Albert and stated that she would take Ksh 3,200,000. The letter was received by Albert at his home on Tuesday morning. At 4.00 pm on Tuesday afternoon, Albert at his office in Westlands wrote a letter to Betty accepting her offer. On his way to post the letter Albert met Cuthbert who told him, ‘I gather that Betty has finally sold her car.’ Betty had, indeed, sold the car. Albert posted his letter and, upon arriving home in Rongai, discovered a message on his answer phone from Betty. The message had been left at 3.00 pm; Betty had stated, ‘I withdraw my offer.’ Albert bought a similar car for Ksh 4,000,000.
Advise Albert.
