A flexible budget adjusts for:

**The reasoning** A flexible budget is like having multiple versions of your budget based on how busy your business gets. Think of it as a "what-if" planning tool. The key principle: **Flexible budgets separate costs into fixed and variable components**, then adjust the variable costs based on actual activity levels (units produced, sales volume, hours worked, etc.). For example, if you budgeted to produce 1,000 units but actually produced 1,200 units, a flexible budget recalculates your expected costs for 1,200 units. This lets you fairly compare actual performance against what you *should* have spent at that activity level. **Why the wrong options tempt you** - **A (Wages only)**: Yes, wages often vary with activity, but flexible budgets adjust *all* variable costs (materials, utilities, commissions), not just wages. - **C (Inflation only)**: That's more about economic adjustments, not operational flexibility. - **D (Foreign exchange only)**: Currency changes are external factors, not the activity-level focus of flexible budgeting. **Quick takeaway** A flexible budget is your "smart" budget that bends with how much work you actually do—it's not stuck on one activity level like a static budget.
