The document compares the expenses and profits of the gym's senior aquatics and youth gymnastics classes in October and November. The senior aquatics classes had higher total fees but similar expenses, resulting in higher profits than the youth gymnastics classes both months. A chart shows that the total profit for senior aquatics over the two months was over $50,000 while youth gymnastics was just under $50,000, indicating the senior aquatics classes were more profitable. The memo discusses adding additional senior aquatics classes on Tuesdays and Thursdays given the profitability and closure of a local senior center.
