Manny agrees to provide pool-cleaning and lawn-care services to Janice in preparation for a party Janice is holding for family and friends. The agreement requires that Janice pay Manny $250.00 for three hours work. After completing approximately half the job, Manny requests that Janice pay him an extra $50.00 because the cost of gasoline used for the lawnmower had gone up that morning. Janice agrees to pay the additional $50.00. Is she legally liable to do so?
◦ Yes, because Manny relied on Janice's promise.
◦ No, because Janice is promising to reward Manny for something he has previously done and past consideration is no consideration.
◦ No, because Manny had an existing contractual obligation to perform the services for $250.00 and there is no consideration for the subsequent agreement to pay $50.00 more.
◦ Yes, because the rising price of gas should be borne by Janice.
◦ Yes, because she told Manny she would pay him and he finished the job on the basis of her promise.
