how do I prepare a second and third set of budgets at the 3,000 and 3,500 level of units using the stable (constant) production schedule suggested by Yun. Note: These should be placed on separate spreadsheets in your workbook and labeled. Prepare the production, purchasing (aluminum), and cash budgets. Hold monthly production constant for the two constant levels suggested by Yun. It will be helpful to change the format of the production budget to begin with budgeted production rather than budgeted sales.
