The entry tickets for a local fair costs $9 for adults and $3 for children. In order for the fairgrounds to earn a profit, they must make at least $500. Viable solutions only include whole numbers. Give one example of a nonviable solution to this situation. 

An example of a nonviable solution would be selling 50 adult tickets and 50 children tickets, as this would only bring in $600, exceeding the profit goal of $500.
