Explanation:
On January we collect the 85,000 from revenues and the 12,00 form marketable securities.
Then, we add up each disbursement:
Materials 50000
Labor       30000
Overhead (net of depreciation) 19,500
Selling and administrative 15000
Total 114,500
Then we solve for the cash balance and get the blaance as it is higher than 20,000 we do not need financing
Then, this value is the beginning cash for February. As the ending balance is 14,000 we will take 6,000 financing to reach the bare minimum of 20,000
