Jane Marks has a restaurant in which she accepts credit cards and checks. Several of the places that Jane shops now accept debit cards and do not accept checks. Jane's banker explained that a debit card would immediately transfer money into her account, but it would cost $50 per month for the equipment and bank charges. Although she requires proper identification, Jane loses approximately $590 a year as a result of bad checks. She also determined that on average she loses 115 days of interest on all checks because the banks are closed on 11 holidays and weekends (52 weeks times 2 weekend days = 104 + 11 holidays). Jane currently earns 3 percent interest on her bank accounts and accepts an average of $2,000 a day in checks.

b. What is the benefit?
c. Should Jane implement the system?
