Problem:
Linkup Systems, which provides investors with computerized information about stock prices, is considering the establishment of a lockbox system with its bank. The firm receives daily remittances of $1.5 million, and could earn 9% on any funds freed up through faster collections. If the lockbox system can save 2 days in the collection process, and the firm's bankers will charge $200,000 per year to operate the lockbox system, is it worth it to establish the system?
