Castor, Inc. is preparing its master budget for the quarter ended June 30. Budgeted sales and cash payments for merchandise for the next three months follow:

Sales are 50% cash and 50% on credit. All credit sales are collected in the month following the sale. The March 30 balance sheet includes balances of $ 12,000 in cash, $ 12,000 in accounts receivable, $ 11,000 in accounts payable, and a $ 2,000 balance in loans payable. A minimum cash balance of $ 12,000 is required. Loans are obtained at the end of any month when a cash shortage occurs. Interest is 1% per month based on the beginning of the month loan balance and is paid at each month end. If an excess balance of cash exists, loans are repaid at the end of the month. Operating expenses are paid in the month incurred and consist of sales commissions (10% of sales), shipping (2% of sales) office salaries ($ 5,000 per month) and rent ($ 3,000 per month). Prepare a cash budget for each of the months of April, May, and June (round all dollar amounts to the nearest wholedollar).
