Jack had a pre-existing legal duty to mow the lawn as per the original agreement for $50. Adding an additional amount of $20 for the same task did not provide any fresh consideration, and therefore, Jill is not obligated to pay the additional amount. This principle is known as the pre-existing duty rule, and it prevents parties from making unilateral modifications to an existing contract.
