What must income not exceed in a diving course budget?

Income in a diving course budget is critical as it directly affects the financial health and sustainability of the course. The correct answer emphasizes that income must not exceed total expenses. This ensures that all costs associated with running the diving course—such as instructor fees, marketing costs, equipment costs, and other operational expenses—are covered. If income exceeds total expenses, it indicates that the course is financially viable and can sustain its operations, pay its staff, and reinvest in necessary resources.

Having a budget where income matches or exceeds expenses is essential for maintaining a profitable program. This principle helps instructors and course organizers to effectively manage their finances, ensuring they do not incur losses and can continue providing quality diving education and experiences.
