Dane Co. purchases raw materials on account. Some of Dane's suppliers do not offer discounts and require payment the month following the purchase. Other suppliers sell on credit terms of 2/10 net 30 , which means that Dane can take a 2% discount and pay 98% of the invoiced amount if the invoice is paid within 10 days. If the invoice is not paid within 30 days of making the purchase, then Dane must pay the full amount (100\%) of the invoice. Dane's policy is to take advantage of available cash discounts by paying on day 10 and to make payments to suppliers who do not offer discounts on day 30 . At the beginning of the year, Dane's account payable balance is $70,000. All available discounts have been taken, and the balance will be paid in January. Given the following planned purchases for the next few months, determine the amount of cash that must be available each month to pay for the firm's purchases
