$595 at 5.5% compounded quarterly for 4 years

You can do it your way zegroes but the interest rate is 5.5/4%= 1.375%

And you don't do it 4 times for 4 years, you do it 16 times for 16 quarters.

does that make sense?

Hang on a minute.  Where did you get 25% from - what has that got to do with anything?

take it by steps do it year by year for example i had a problem like this today alright lets say you had 1,000 dollars in the bank ok now one year at a time...so you start off with 25 percent intrest every year for four years you would end up with 1,025 dollars at the end of the first year and it countinues until you hit the fourth year same with this question..just start with 595 then add 5.5 percent of intrest every year for 4 years and you will get the answer.

So we have

595(1 + .055/4)^4x4

Where

595 is the amt invested

.055 is the interest rate expressed as a decimal

The "4" inside the parenthesis represents the number of compoundings per year - 4

And the first exponent of "4" represents the time, in years

And the second exponent represents the compoundings per year - 4

So we have, in dollars

$$\mathrm{\ }$$ $${\mathtt{595}}{\mathtt{\,\times\,}}{\left({\mathtt{1}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{0.055}}}{{\mathtt{4}}}}\right)}^{\left({\mathtt{4}}{\mathtt{\,\times\,}}{\mathtt{4}}\right)} = {\mathtt{740.305\: \!270\: \!404\: \!234\: \!410\: \!8}}$$

≈ $740.31

It was an example sorry i thought i mentioned that in my post?
