The expected net income assuming 400 people buy tickets

The Parent Teacher Organization (PTO) of Brevard County High School is planning a fund-raising campaign. The PTO is considering the possibility of hiring
Charlotte Hale, a world-renowned investment counselor, to address the public. Tickets would sell for $36 each. The school has agreed to let the PTO use the
high school auditorium at no cost. Mrs. Hale is willing to accept one of two compensation arrangements. She will sign an agreement to receive a fixed fee of
$10,400 regardless of the number of tickets sold. Alternatively, she will accept payment of $26 per ticket sold. In communities similar to that in which
Brevard County is located, Mrs. Hale has drawn an audience of approximately 400 people.
