Problem-solving: Assuming zero taxes, calculate the present value of a $1000 of future income, compounded annually, to be received at the end of: a) one year, using a discount rate of 5%;

b) one year, using a discount rate of 10%;

c) five years, using a discount rate of 5%;

d) five years, using a discount rate of 10%;

e) twenty years, using a discount rate of 20%.

I think I am over complicating this because i freak out when it comes to math.
