Kathy plans to move to Maryland and take a job at McCormick as the assistant director of HR. She and her husband, Stan, plan to buy a house in Garrison, MD, and their budget is $500,000. They have $100,000 for the down payment and McCormick will pay for closing costs. They are considering either a 30-year mortgage at 4.5 percent annual rate or a 15 year mortgage at 4 percent. Calculate the monthly payment for each using the PMT function.
