I need help calculating this problem in excel using the formula, financial function. I keep getting a negative Annual Interest Rate. Can you please help with the names of the columns for the data entered and the function used and whether the numbers should be entered as negatives? - Thx

You are considering leasing a car. You notice an ad that says you can lease the car you want for $477.00 per month. The lease term is 60 months with the first payment due at inception of the lease. You must also make an additional down payment of $2,370. The ad also says that the residual value of the vehicle is $20,430. After much research, you have concluded that you could buy the car for a total "drive out" price of $33,800. What is the quoted annual interest rate you will pay with the lease?
