You just turned 22 years old and want to retire when you turn 65. You plan to put $3,000 every year into a ROTH IRA, a retirement account from which you can withdraw money after retirement without having to pay any taxes. You expect to earn a return of 5% on your investments every year.

How much money can you expect to have at age 65 if you make your first deposit now and your last one on the day you turn 64?

2)You took out a 30-year fixed-rate mortgage to buy a house. The interest rate is 2.4% (APR) and you have to pay $1,900 per month (at the end of each month).

What is the original mortgage amount?
