Management uses various control ratios, including capacity, activity, efficiency, and calendar ratios, to monitor performance. These ratios provide a quantitative basis for comparing actual results against budgeted targets, allowing for the identification and analysis of variances in operational performance.

Performance budgeting (a-2) focuses on production or output orientation. Zero-based budgeting (b-3) is famously associated with Jimmy Carter's administration. A master budget (c-4) acts as the summary of all functional budgets. A fixed budget (d-1) remains unchanged regardless of the actual level of activity attained during the period.

May cash inflow includes: 40% of May sales (22,000), 70% of April credit sales (60% of 70,000 = 42,000) minus 2% discount (42,000 * 0.98 = 41,160 * 0.7 = 28,812), and 27% of March credit sales (60% of 60,000 = 36,000 * 0.27 = 9,720). Summing these: 22,000 + 28,812 + 9,720 = 60,532.

A flexible budget is designed to adjust based on varying levels of activity. Because it separates costs into fixed and variable components, it allows management to accurately forecast expenses at different production volumes, making it the most appropriate tool for this distinction.

A cash budget is a financial planning tool that forecasts the expected inflows and outflows of cash for a business over a designated period. It helps management ensure sufficient liquidity to meet operational obligations and identify potential cash surpluses or deficits.

Zero-based budgeting is a method where all expenses must be justified for each new period. The process starts from a 'zero base,' meaning every function within an organization is analyzed for its needs and costs, regardless of whether the budget is higher or lower than the previous one.

The sales volume variance measures the difference between the static budget (based on planned volume) and the flexible budget (based on actual volume). By subtracting the static budget of $6,000 from the flexible budget of $15,000, we arrive at a variance of $9,000. This variance highlights the impact of changes in sales volume on the company's financial performance, independent of price or cost efficiency fluctuations.

A budget is a comprehensive financial plan that quantifies a company's expectations for a defined period, typically one year. It encompasses projected sales volumes, revenues, resource requirements, costs, expenses, assets, liabilities, and cash flows. By formalizing these expectations, a budget acts as a control mechanism that allows management to compare actual performance against planned targets, facilitating better decision-making and accountability throughout the organization.

The static budget amount is determined by subtracting the sales budget variance from the flexible budget amount. A static budget is prepared based on a single level of activity before the period begins. By removing the volume-related variance from the flexible budget, which is adjusted for actual activity, we reconcile the figures back to the original static plan.

The production budget is calculated by taking the budgeted sales units, adding the target ending finished goods inventory, and subtracting the beginning finished goods inventory. This calculation determines the total number of units that must be manufactured during a specific period to satisfy customer demand and maintain desired inventory levels. It is a fundamental component of the master budget, linking sales forecasts to production requirements.
