Problem 2. Alejandro is currently taking a course in personal finance and has learned the benefits of both starting a savings plan and starting it early. Therefore, he has decided to save $840 per year in an account that pays 5% . He plans to open the account tomorrow and will make deposits at the end of each year, including this year, for the next 25 years. (Note: Round your answer to the nearest whole dollar.)

I got the answer to work using an interest factor chart but I can't make it work using the the equation FV=PV*(1+ i)^n.When I use the equation I get 2844 but with the chart method I get 40091.I can't figure out if I am missing a step with the equation route.This is what I need help with because I can't find an example for it.

Thanks
