Please HELP ASAP! Need functions!

In all problems, remember to use functions in Excel, and cell references when answering the questions. Problem 1: (10 points) Mr. Bill Buffett has lately started selling used cars. He has asked you to make a simple application for him to keep track of the monthly payments that he should receive from every customer. Use Excel functions to provide some analysis for Mr. Buffett. His current customers, their credit score, and vehicle prices are provided in the table in the worksheet "Problem 1." Add additional columns that provide the necessary numbers. For purchasing a used car, the customer's credit score will determine the available term of the loan, interest rate, and percent of the purchase price required as a down payment. For each customer, find the appropriate down payment, amount financed, loan term (months), and interest rate. Financing information is contained in the worksheet "Financing Table". Do not copy and paste the table to the "Problem1" worksheet. You need to refer to the cells of this table. Finally, calculate the Monthly payment for each loan.
