I need the answer to this questions. It has to do with money and banking and might also need some formulas

1) If the rate of discount is 20 percent,

a. Would you rather receive $100 today or $120 in one year.

b. Would you rather receive $205 today or $240 in one year.

c. Would you rather receive $500 today or $610 in two year.

2) You have just won a $25 million lottery prize, which pays you $1 million (tax-free) every year for the next 25 years. Have you really won $25 million? What have you won if the rate of discount is 5%? You will get your first $1 million payment today and your last $1 million payment 24 years from now.

3) Your newest book, "50 Shades of Gray Recession

Bars," is being considered by a publishing house, which offers you an advance of $100,000 today, plus $50,000 at the end of each of the next two years. Call this Plan A.

a. What is the present value of the payments from the publisher, given your rate of discount is 2 percent? Show your work. You may round to the nearest dollar.

Your literary agent thinks you should make a counteroffer, in which you receive nothing today but receive $3 at the end of each of the next two years for each book you sell during

the year. Call this Plan B.

b. If you think you will sell 35,000 books a year during each of the next two years, what is the present value of your earnings under Plan B? Show your work. You may round to the

nearest dollar.

c. If your publisher thinks you will sell 30,000 books a year during each of the next two years, what is the present value of your earnings under Plan B? Show your work. You may

round to the nearest dollar.

d Which plan is best for you, based on your expected sales? Which plan is best for your publisher, based on its expected sales? Which plan will you and your publisher agree to, or

will you have to negotiate further? Explain.

4) Which would you rather be holding if there is a decline in interest rates: a debt security that matures in 10 years or one that matures in three months? Why? (Note: Assume that the interest rates on both securities change by the same amount; for example, suppose that both fall by 2 percentage points.)
