I ONLY NEED HELP ON QUESTION 3. QUESTION 2 IS ONLY POSTED SO YOU HAVE THE INFORMATION.

2) Your clients, Tom and Melissa Sampson (age 40), want to retire when they are 65 and want to provide 30 years of income during retirement. Based on their current level of living, they would like to provide for $75,000/year (in current dollars) during retirement. They currently have $150,000 in Roth IRAs. Social Security will provide $30,000/year in current dollars. They have made the following rate estimates: 3.0% inflation before and after retirement, 7.0% return on investments before retirement, and 5.0% return on investments after retirement.
