You have just made an offer on a new home and are seeking a mortgage. You need to borrow $600,000. a. The bank offers a 30-year mortgage with fixed monthly payments and an interest rate of 0.5% per month. What is the amount of your monthly payment if you take this loan? b. Alternatively, you can get a 15-year mortgage with fixed monthly payments and an interest rate of 0.4% per month. How much would your monthly payments be if you take this loan instead?

*A.1. This problem is from the Appendix to Chapter 4. Your grandmother bought an annuity from Rock Solid Life Insurance Company for $200,000 when she retired.

How long must she live after the day she retired to come out ahead (that is, to get more in value than what she paid in)?
