Built-Tight is preparing its master budget. Budgeted sales and cash payments follow: Sales to customers are 30% cash and 70% on credit. Sales in June were $60,500. All credit sales are collected in the month following the sale. The June 30 balance sheet includes balances of $27,000 in cash and $5,600 in loans payable. A minimum cash balance of $27,000 is required. Loans are obtained at the end of any month when the preliminary cash balance is below $27,000. Interest is 1% per month based on the beginning-of-the-month loan balance and is paid at each month-end. Any preliminary cash balance above $27,000 is used to repay loans at month-end. Expenses are paid in the month incurred and consist of sales commissions (10\% of sales), office salaries ( $4,600 per month), and rent ( $7,100 per month). 1.
