I need help with finding the right formulas to use in an Excel spreadsheet for the following formula:

A car manufacturing company offered a choice of a 0% loan for 60 months, or $5000 cash back on the purchase of a $29,061 car. a) If someone took the 0% loan offer, how much will the monthly payment be? b) If someone took the $5000 cash-back offer and can borrow money from their local bank at 6% interest compounded monthly for 5 years, how much will the monthly payment be? (Assume you use the cash-back offer as a down payment on the car) c) Which of the 2 offers is more favorable?
