Can someone show me how to calculate this? Need lump sum at age 65 and annuity payment?

PV=54000

Ri=0.05

n=45 (Age 21 to age 66)

FV=485190.42084861

This is correct for the first part. I got confused when it change to "start investing at 30".

What is the Lump Sum and Annuity Payment? Assume you are now 21 years old and will start working as soon as you graduate from college. You plan to start saving for your retirement on your 25th birthday and retire on your 65 th birthday. After retirement, you expect to live at least until you are 85 . You wish to be able to withdraw $54,000 (in today's dollars) every year from the time of your retirement until you are 85 years old (i.e., for 20 years). The average inflation rate is likely to be 5 percent. Now assume you start investing for your retirement when you turn 30 years old and analyze the situation under rate of return assumptions of (i) 8 percent, (ii) 10 percent, and (iii) 15 percent. (Round answers to 0 decimal places, e.g. 1,525.)
