PLEASE HELP ME!!!!!!!

Part 1 (1 point):

You wish to retire at age 50 and figure you need $75,000 per year in retirement in todays dollars.

Assume that payments are at the beginning of the year (as opposed to monthly to simplify).

How much do you need when you turn 50 to meet your retirement dream?

Assume no increase in annual payments during retirement.

Also assume a life expectancy of 100 years (you will live to 100).

Also assume a discount rate of 5%

Part 2 (1 point):

What if inflation during retirement is 2% per year, how much do you now need?

Part 3 (2 point): You decided to purchase a shore house at age 40 for $500,000 all CASH - which you took out of your retirement savings - You obviously forgot about the 99 principles Due to insurance, utilities, taxes, etc; this will add $25,000 per year in retirement and same inflation assumption (assume 2%). How much does this add to your required amount at 50 in the above two parts. Hint: add the $25,000 to your expected cash flow in retirement Part 4 (1 points): Had you not bought the house at the shore at 40, how much would you have at age 50? Remember you have 10 years in your 40s where you paid the $25,000 in costs plus the $500,000 you removed from the retirement account. Assume a discount rate of 5% (do not worry about inflation)
