Hello, I need some help with this following question. "You deposit $100 each month into a savings account that pays 5.5% compounded monthly. How much interest will you have earned after 7 years?"
 
Another question

Thank you. I tried to do a similar problem, with only small differences. This is it. "You deposit $130 each month into a savings account that pays 5.5% compounded monthly. How much interest will you have earned after 8 years?"

How is this so far?

A=P(1+r)^n

A=130(1+0.055)^96
=22191.13304
=22,191.13 INTEREST

I'm terrible at math, I have no idea if this is even close to the answer.
 
WHY are you using that formula?
The formula shown is CLEARLY : F = P[(1+i)^n - 1] / i
