Cash budgeting. How do I do this?? Any explanation would be greatly appreciated

Karim Corp. requires a minimum $9,900 cash balance. If necessary, loans are taken to meet this requirement at a cost of 2% interest per month (paid monthly). Any excess cash is used to repay loans at month-end. The cash balance on July 1 is $10,300 and the company has no outstanding loans. Forecasted cash receipts (other than for loans received) and forecasted cash payments (other than for loan or interest payments) follow. 3 July August ep Cash receipts Cash payments $25,900 $33,900 41,900 30, 850 31,900 33,900 Prepare a cash budget for July, August, and September (Negative balances and Loan repayment amounts (if any) should be indicated with minus sign.
