Sales are made on a cash basis only. Koehl's purchases must be paid for during the following month. Koehl pays herself a salary of $4,600 per month, and the rent is $2,100 per month. In addition, she must make a tax payment of $12,000 in December. The current cash on hand (on December 1) is $850, but Koehl has agreed to maintain an average bank balance of $4,500 - this is her target cash balance. (Disregard the amount in the cash register, which is insignificant because Koehl keeps only a small amount on hand in order to lessen the chances of robbery.) The estimated sales and purchases for December, January, and February are shown below. Purchases during November amounted to $140,000.

Sales December $130,000, Purchases $25,000

Sales January 34,000, Purchases 25,000

Sales February 66,000, Purchases 25,000

Suppose Koehl starts selling on a credit basis on December 1, giving customers 30 days to pay. All customers accept these terms, and all other facts in the problem are unchanged. What would the company's loan requirements be at the end of December in this case?
