Hey, this is my first finance class, ever! & I would really appreciate any help that you can give me.

Can you please assist me with the workings to the following questions...

Ive see many people post different answers and I'm not quite sure how they came to their reasoning.

I'm using the Excel FX.

The questions are attached.

Thank you for your help.

1. If you save and invest $200 a month for the next 10 years for your 8-year old child, how much money would you have in your child's 529 plan in 10 years if the plan's average return is 9% p.a.? What if you can invest $300 a month? 2. Your father wants to give you some money and he lets you to choose one among the three following payments: A. $100,000 today B. $10,000 at the beginning of each year (starting today) for the next 15 years C. $150,000 five years later Which method would you prefer if your opportunity cost of money is 8% p.a.? 3. Your friend is kind enough to lend you $30,000 today so that you can start a small business. She is giving you three payment plan choices. Which payment plan is the most favorable to you? A. Pay back a lumpsum amount of $50,000 in 5 years. B. Pay back $10,000 a year for the next 4 years, with the first payment starting 1 year from today. C. Pay back $1,000 a month for the next 4 years, with the first payment starting 1 month from today. 4. You wan to retire when you accumulate $2,000,000 in your 401(k) account that returns 10% p.a. on average. If your current 401(k) balance is $250,000 and you want to invest $500 a month, when can you retire (in number of months)? How about investing $700 a month? 5. You are shopping for a car and got quotes for the same kind of car on financing terms from three different South Florida dealers. All quote the same price of $30,000 with no down payment. Dealer A. 0.9% financing for 60 months; Dealer B. 1.9% for 72 months Dealer C. 0.0% for 36 months (1) Which deal will have the least amount of monthly payment? (2) Also, which deal is the best for you, financially speaking? (3) Why do you think that is the best option for you
