Wawatu on seeing the advertisement visited Wakalinga's house today in the moming to see a Laptop. After discussion, Wakalinga offered to sell a Laptop to Wawatu for Tshs 1,500,000%. Wawatu stated that he would need some time to think it over but if Wakalinga had heard nothing from Wawatu by tomorrow evening she could assume that Wawatu had bought it. Wakalinga replied that this arrangement was fine by her. At 3 p.m today afternoon Mbogo telephoned Wakalinga and offered to buy laptop for Tshs. 2,500,000/-. Wakalinga immediately accepted Mbogo's offer and telephoned Wawatu. As Wawatu was out of line, Wakalinga send a message to Wawatu's handphone revoking his original offer. Unknown to Wakalinga, the sent message was not received by Wawatu. Wakalinga however was still worried about the situation and tried to call Wawatu again at 5 pm this evening. This time Wakalinga spoke to Wawatu's wife, and told her that the laptop had been sold. The wife said that she expected Wawatu to be back home at 7pm and would pass the message on to him.

Wawatu came home at 7.30pm and his wife then gave him message from Wakalinga. Advise Wakalinga [8 marks]
