state whether consideration is present from both Dale and John (just write Yes or No; ignore other issues such as Intention) and

state the rule and the case that best support your decision.

1On Monday Dale agrees to clean John's windows the following Friday for $100. The day before she is due to do the job she is offered $300 to clean another person's windows. She phones John to say that she will be unable to do the agreed work. John is desperate to get the windows cleaned before he hosts a big party at his home on the Saturday so he offers Dale an additional $200 if she does the agreed job on Friday.
