Step-by-step explanation:
The budget type that requires an athletic trainer to list anticipated expenditures for specific categories of program subfunctions, such as equipment repair, insurance, and expendable supplies, is the line-item budget. This type of budgeting method allows for clear and organized reporting of expected costs in various predetermined categories, thereby facilitating easier tracking and management of funds within an athletic program or department. Each category lists individual line items with estimated costs, giving a detailed breakdown of expenses for better financial planning and accountability.
