Consideration: Rule: Consideration requires a bargained- for-exchange and legal value. Analysis: Legal value requires a promise, performance and or a promise to refrain from doing something that a person has a legal right to do. There is a performance of an action that one is not to obligated to undertake if Jill paints Jack's window. Furthermore, Jack is also promising to do something that he does not have a prior legal duty to do. This is because there is nothing obliging him to offer Jill fifty dollars to paint \"Grand lie-Opening\" on Jack's window. Abargained for exchange needs an item of value to begin or promised by the promiser in return for the performance. An item of value is being given or promised by the promiser because Jaci-r promised to pay Jill fty dollars if she paints the requested saying on Jack's window during the weekend. Jack's promise is given in return for the promisee's promise because if and or when Jil begins to paint the message on Jack's vrdndowa she is accepting his primes of fifty dollars and that will be sa'dsfying her part of the exchange. Therefore there is consideration. Conclusion: Based on the analysis, Jill intends to enter in an unilateral contract with Jack
