(2) All other budgeted costs are treated as variable costs, based on the expected number of customers. Yumi Co currently adopts an incremental approach to budgeting, with the annual budget figures for each year being based on the previous year's figures. However, a new finance director has recently joined the company, and he has questioned whether this is suitable for all Yumi Co's restaurants.
