Trying to set up equation for problem!!!

I need assistance setting up the equation for this problem...Thanks!!!



A businesswoman wants to invest a certain sum of money at the end of each year for 5 years. The investmet will earn 6% compounded annually. At the end of 5 years, she will need a total of $30,000 accumulated. How should she compute the required annual investment?

a) $30,000 times the amount of an annuity of $1 at 6% at the end of each year for 5 years
b) $30,000 divided by the amount of an annuity of 41 at 6% at the end of each year for 5 years.
c) $30,000 times the present value of any annuity of $1at 6% at the end of each year for 5 years.
d) %30,000 divided by the present value of an annuity of $1 at 6% at the end of each year for 5 years.

isn't it something like this?

(x is the variable of equation)
note f(1)=x
note f(2)=f(1)*106/100
note f(y)=f(y-1)*106/100

final equation: f(1)+f(2)+...f(6)=30000

hmph... :rolleyes:
