I need help with this whole problem, thank you.

Karim Corporation requires a minimum $8,000 cash balance. Loans taken to meet this requirement cost 1% interest per month (paid at the end of each month). Any preliminary cash balance above $8,000 is used to repay loans at month-end. The cash balance on July 1 is $8,400, and the company has no outstanding loans. Budgeted cash receipts (other than for loans received) and budgeted cash payments (other than for loan or interest payments) follow. Cash receipts Cash payments.
