You purchased $3,782 worth of office equipment on a deferred payment plan. The plan allows you to make no down payment, and there is no payment at all for 6 months. If the entire $3,782 is paid in full before the 6 months is up, there is no interest. If it is not paid in full within the 6 months, there is a finance charge with an APR of 22.3% applied each month going back to the first month. If you make the full payment a week after the 6 months expired, what is the finance charge?
