Step 1: Calculate total cash inflows for each month.
- Jan Inflows = $10,000 (cash sales) + $4,000 (Dec credit sales) = 14,000
- Feb Inflows = $12,000 (cash sales) + $5,000 (Jan credit sales) = 17,000
- Mar Inflows = $15,000 (cash sales) + $6,000 (Feb credit sales) = 21,000
Step 2: Calculate total cash outflows for each month.
- Jan Outflows = $8,000 (payments) + $3,000 (rent) = 11,000
- Feb Outflows = $9,000 (payments) = $9,000
- Mar Outflows = $11,000 (payments) = $11,000
Step 3: Calculate monthly net cash flow and closing balance.
- January:
- Net Cash Flow = 14,000−11,000 = 3,000
- Closing Balance = $5,000 (opening) + $3,000 = 8,000
- February:
- Net Cash Flow = 17,000−9,000 = 8,000
- Closing Balance = $8,000 (opening) + $8,000 = 16,000
- March:
- Net Cash Flow = 21,000−11,000 = 10,000
- Closing Balance = $16,000 (opening) + $10,000 = **26,000∗∗
The closing cash balance for March is **26,000∗∗.
