Problem 7-25 Apollo Data Systems is considering a promotional campaign that will increase annual credit sales by $610,000. The company will require investments in accounts receivable, inventory, and plant and equipment. The turnover for each is as follows: Accounts receivable Inventory Plant and equipment All $610,000 of the sales will be collectible. However, collection costs will be 4 percent of sales, and production and selling costs will be 78 percent of sales. The cost to carry inventory will be 7 percent of inventory. Amortization expense on plant and equipment will be 8 percent of plant and equipment. The tax rate is 20 percent. Inventory is calculated using sales and not cost of goods sold.
