Cecilia purchased $4,322 worth of home appliance on Best Buy Deferred payment plan. The plan allows the customer to make no down payment, and there is no payment at all for 3 months. If the entire $4,322 is paid in full before the 3 months is up, there is no interest. This is a store’s way to persuade customers to make purchases. If it is not paid in full within the 3 months, there is a finance charge with an APR of 21.6% applied each month going back to the first month. If Cecilia makes the full payment a week after the 3 months expired what is the finance charge?
