Please, complete problems, exploration and questions below (total points-14).
1. Marshall, Ch. 6, problem 6-26 a, b, c & d (5 points total: 1.25 point per
problem)   Present value calculations.   Using a present value table, your calculator or a computer program present value function, answer the following questions:

a. What is the present value of nine annual cash payments of $4,000, to be paid at the end of each year using an interest rate of 6%   Using my excel chart I get the following answer:
     
        PV -                 4,000
                    Years                 9
                    Discount rate     6%
                              =           $2,367.59

b. What is the present value of $15,000 to be paid at the end of 20 years, using an interest rate of 18%?  

I used my formula on this problem also in excel.
    PV -                   15,000
    Years                   20
          Discount rate       18%
                  =                 $547.58   (or $548 if rounded out)

c. How much cash must be deposited in a savings account as a single amount in order to accumulate $300,000 at the end of 12 years, assuming that the account will earn 10% interest?

The excel formula was used here also.
PV -                   300,000
            Years                   12
            Discount rate       10%
        =                 $ 95,589.25 (or 95,589 rounded out)

d. How much cash must be deposited in a savings account (as a single amount) in order to accumulate $50,000 at the end of seven years, assuming that the account will earn 12% interest?

I used my excel formula to get answer.
PV -                   50,000
Years                   7
Discount rate       12%
        =                 $ 22,617.46 (or 22,617 if rounded out)
