please answer!

Suzie wants to have $1,000,000 in the bank in thirty years. If the bank pays interest at 6% compounded semi-annually, how much does she need to deposit today to reach her goal? Matthew wants to withdraw $1,000 per month for the next 5 years. He will withdraw his first amount in one month. The bank pays interest at 12% compounded monthly. How much does he need to deposit today to do this? Heather hit the lottery!! She has the option of taking 560,000 today or 100,000 per year for the next 8 years, or $1,000,000 in ten years. If she can deposit her money at 8%, ignoring taxes, which deal should she take
