Final answer:
Continuous budgets are more expensive to maintain than single-period budgets because of the additional time and effort required in their preparation.
Step-by-step explanation:
Continuous budgets are generally more expensive to maintain than single-period budgets because more time and effort is required in their preparation. Continuous budgets involve planning and forecasting for multiple periods, such as months or years, compared to single-period budgets that cover only one period, like a single month. The continuous budgeting process requires ongoing monitoring and updating, which can increase the cost of maintenance.
