An investment will provide you with $100 at the end of each year for the next 10 years. What is the present value of that annuity if the discount rate is 8% annually?

What is the present value of the above if the payments are received at the beginning of each year?

If you deposit those payments into an account earning 8%, what will the future value be in 10 years?

What will the future value be if you open the account with $1,000 today, and then make the $100 deposits at the end of each year?

I need all parts answered please.
