An abbreviated cash budget for Big Chuck Enterprises follows. Big Chuck wishes to maintain a $10,000 minimum cash balance at all times. Additional financing is available (and retired) in $1,000 multiples at a 12% interest rate. Assume that borrowings take place at the beginning of the month; retirements, in contrast, occur at the end of the month. Interest is paid at the time of repaying principal and computed on the portion of principal repaid.
