## Sharpe Corporation cash budget, compound interest, present value, annuity

Please complete the attached 5 study problems and show your work.

4-6A. (Cash budget) The Sharpe Corporation's projected sales for the first eight months of 2004
are as follows:
January \$ 90,000 May \$300,000
February 120,000 June 270,000
March 135,000 July 225,000
April 240,000 August 150,000

Of Sharpe's sales, 10 percent is for cash, another 60 percent is collected in the month following sale, and 30 percent is collected in the second month following sale. November and December sales for 2003 were \$220,000 and \$175,000, respectively.

Sharpe purchases its raw materials two months in advance of its sales equal to 60 percent of their final sales price. The supplier is paid one month after it makes delivery. For example, purchases for April sales are made in February and payment is made in March.

In addition, Sharpe pays \$10,000 per month for rent and \$20,000 each month for other expenditures. Tax prepayments of \$22,500 are made each quarter, beginning in March.

The company's cash balance at December 31, 2003, was \$22,000; a minimum balance of \$15,000 must be maintained at all times. Assume that any short-term financing needed to maintain the cash balance is paid off in the month following the month of financing if sufficient funds are available. Interest on short-term loans (12 percent) is paid monthly. Borrowing to meet estimated monthly cash needs takes place at the beginning of the month. Thus, if in the month of April the firm expects to have a need for an additional \$60,500, these funds would be borrowed at the beginning of April with interest of \$605 (.12 × 1/12 × \$60,500) owed for April and paid at the beginning of May.

a. Prepare a cash budget for Sharpe covering the first seven months of 2004.
b. Sharpe has \$200,000 in notes payable due in July that must be repaid or renegotiated for
an extension. Will the firm have ample cash to repay the notes?
