Apply problem solving methods and analyze solution of financial problems.
1.) You deposit $100 into an account earning a 10% annual rate of interest. How much money will you have in the account at the end of five years?
2.) You have just won the lottery and have a choice of receiving a lump sum of $1,000,000 or an annuity of $100,000 per year for 15 years. If the appropriate discount rate is 8%, which alternative would you choose? Explain.
3.) What happens to the future value of a sum of money deposited for N years as the rate of return k increases? What happens to the present value of a sum of money to be received at the end of N years as k increases?
Question 1:
PV = Deposit Amount = $100
r = annual rate of interest = 10%
n = 5 years
Account balance in 5 years = PV * (1+r)^n
= $100 * (1+10%)^5
= $100 * 1.61051
= $161.051
Therefore, balance in the account in 5 years is $161.05
Question 2:
Option a:
Lump sum payment = $1,000,000
Option b:
P = annual receipt = $100,000
n = 15 years
r = discount rate = 8%
Present Value of future cash flows = P * [1 - (1+r)^-n] / r
= $100,000 * [1 - (1+8%)^-15] / 8%
= $100,000 * 0.684758295 / 0.08
= $855,947.869
= $855,947.87
It is bettet to accept lump sum amount of $1,000,000 today
Question 3:
What happens to the future value of a sum of money deposited for N years as the rate of return k increases - Future value will increase as future value and rate of interest has positive relationship
FV = Sum Deposited * (1+r)^n
What happens to the present value of a sum of money to be received at the end of N years as k increases
Present value will increase as present value and rate of interest has inverse relationship
PV = Sum to be received / (1+r)^n
