(Preparation of a cash budget) Harrison Printing has projected its sales for the first eight months of 2014 as follows: Harrison collects 20 percent of its sales in the month of the sale, 50 percent in the month following the sale, and the remaining 30 percent two months following the sale. During November and December of 2013, Harrison's sales were $220,600 and $175,200, respectively. Harrison purchases raw materials two months in advance of its sales equal to 65 percent of their final sales price. The supplier is paid one month after delivery. Thus, purchases for April sales are made in February and payment is made in March. In addition, Harrison pays $10,200 per month for rent and $19,600 each month for other expenditures. Tax prepayments of $22,500 are made each quarter beginning in March. The company's cash balance as of December 31, 2013, was $22,300; a minimum balance of $20,000 must be maintained at all times to satisfy the firm's bank line of credit agreement. Harrison has arranged with its bank for short-term credit at an interest rate of 12 percent per annum (1 percent per month) to be paid monthly. Borrowing to meet estimated monthly cash needs takes place at the end of the month, and interest is not paid until the end of the following month. Consequently, if the firm were to need to borrow $50,000 during the month of April, then it would pay $500 ($50,000 >
