You have just been offered a job. You have the choice of two different salary arrangements. You can have 55,000 per year for the next two years, payable at the end of each year; or you can have 40,000 per year for the next two years, payable at the end of each year, along with a signing bonus of 25,000 payable today. If the interest rate is 6% compounded monthly, which do you prefer?
