Summer works as a part-time transcriptionist for the local coroners office. Summer is new to the job; she was hired because the coroner had a huge backlog of cases. Summer agrees to transcribe the entire backlog of 45 cases for $1,575, or $35 per case, and to complete the job within two weeks. The coroner agrees and is anxious to have the work completed. Three days before the deadline, the coroner contacts Summer and says that he will pay her an extra $500 if she completes the job before the deadline. Delighted, Summer agrees and completes the project. Upon receiving the reports, the coroner pays Summer $1,575. If Summer sues for the remaining $500:

-she will win because she had a preexisting contractual duty to complete the reports, and no additional consideration is being provided by the coroner.

-she will lose because she had a preexisting contractual duty to complete the reports, and no additional consideration is being provided by Summer.

-she will win because she had a preexisting contractual duty to complete the reports, and no additional consideration is being provided by Summer.
