Bill invests £500 on the 1st Jan 2004 at a compound interest of R% per annum. The value, £V, of this investment after n years is given by the formula V=500x(1.045)^n

Write down the value of R

This formula usually looks like

$\displaystyle A=P\left(1+\frac{r}{100}\right)^n$

therefore your rate is 4.5 - Jan 6th 2010, 12:28 PMMukilab

Can you go through the actual process?

Ok A=P(1+$\displaystyle \frac{r}{100})^{n}$

So

$\displaystyle A=500(1+\frac{r}{100})^{n}$

Let's say n = 2

$\displaystyle A=500(1+\frac{r}{100})^{2} A=500(2+\frac{2r}{200}??? $ - Jan 6th 2010, 12:50 PMpickslides

So I need a value for A? They just say that the value is V.

I'll post the actual question when I find it, although I think it is unnecessary as I have posted all the core parts that I need answering, I am sure I have not missed something out - Jan 7th 2010, 07:58 AMe^(i*pi)
