Question1:

A)

You are currently 25 years old. You plan to retire when you are 60. You guess

that you will need to support yourself for 30 years after your retirement and that you will

need around $80000 per year. You currently have $50000 already invested in the stock

market which you estimate will make an average return of 7% going forward. You also

plan to put money aside each month into a savings account that earns interest of 3% per

year. After you retire you will put all your money into a retirement account that earns 2%

per year. If you want to be able to withdraw $80000 per year from this account after you

retire such that you have O dollars in the account on your 90th birthday, how much do

you have to save per month while working?

B) You have $1000 that you want to put into a savings account. You have the following options.

a. Bank A offers an account that pays interest quarterly with an APR of 10%

b. Bank B offers an account that pays interest daily with an APR of 9.1%

c. Bank C offers an account that pays interest yearly with an APR of 10.5%

d. Bank D offers an account that pays interest monthly with an APR of 9.7%

What will the difference in dollars be between investing the $1000 for one year in the best option versus the worst option?
