Need help on the following questions. My answer is in bold (which were wrong). Thank you.

Elin wants to retire in 20 years when she turns 60. Elin wants to have enough money to replace 120% of her current income less what she expects to receive from Social Security. She expects to receive $20,000 per year from Social Security in todays dollars. Elin is conservative and wants to assume a 6% annual investment rate of return and assumes that inflation will be 3% per year. Based on her family history, Elin expects that she will live to be 95 years old. If Elin currently earns $100,000 per year and expects her raises to equal the inflation rate, approximately how much does she need at retirement to fulfill her retirement goals?

$3,880,831.

$3,930,814.

$3,997,256

$4,045,303.
