Donna Deposited money onto an account that pays 8% per annum, compounded quarterly. When she goes back 3 years later she discovers 1585.30 in her account.

So Here is my question, I know the formula A=P(1+i)^n but do not know what values to put in for i or n

I have so far 1585.30=P(1+0.2)^3 but I am pretty sure that is incorrect, please help. I do not need the answer I can figure that out on my own, I am just having difficulty understanding what to use for i and n. The book is not real good at explaining things.
