Zach wishes to accumulate $50,000 in a fund at the end of 20 years. If he deposits $100 + x in the fund at the end of every 3 months for the first 10 years and $100 in the fund at the end of every 3 months for the second 10 years, find x to the nearest dollar if i(4) = .04. Express the answer in terms of present value annuity symbols (a or adoubledot) and then evaluate numerically. The answer is given as $520. I'm not really clear on the present value annuity symbols and how they're supposed to be set up so any help would be great thanks!

Sorry, I don't know the symbols myself  though I could solve the problem without. Maybe try myfinanceforum (link at the top of the page)?
