Dante's friend presented her with an investment opportunity.If Dante deposits an amount in the investment now, she will receive annual payments of $25,000 for 15 years, starting 10 years from today.What is the maximum Dante should deposit in the investment if she requires an 7% return? Round all calculations to the nearest dollar.

This question is really hard for me to rap my mind around. Can you help me understand how I can compute this on a calculator?
