Please have issues/facts in the case and then state the case for each potential Respondent/Defendant, cite law/legal code and case law based in precedent where applicable in your explanation.

Joanne is a nurse who needed a job and she knew the local elementary school needed to fill the vacant school nurse position. She contacted the school district president who was authorized to fill the position and offered to be the school nurse for weekly compensation of $1,000 from September to June. The president agreed to consider the offer and subsequently responded to Joanne in writing stating that he agreed to hire her as school nurse for the compensation of $200 per day. Discuss in detail whether there is a valid contract between Joanne and the school.
