The competition was part of the Entrepreneurship Challenge, a contest held at high schools throughout the state.
The St. Joseph School District was well represented at the competition sending eight teams out of the twenty that attended.
Groups had three hours to develop a private-sector business plan.
"It kind of gave that personalized feel where we got to work in a small personalized group and just do what we thought needed to be done," Central High School senior Max Mitchem said.
Isaac Collins attended the event as a facilitator.
"This is really important," he said. "It gives them a chance to be an entrepreneur."
Winners of the competition will receive a $1,000 scholarship if they decide to attend Missouri Western State University.
