Re: can somebody help me with this math problem?

So the 2nd part can be written as (1200/0.017)*(1.017^n - 1)
expand it to get (1200/0.017)(1.017^n) - 1200/0.017
move the -1200/0.017 to the other side of the equal sign and with some factoring you will get

1200/0.017 = (1.017^n)*(16160.35 - 1200/0.017)

isolate 1.017^n on one side of the equation.

Use logarithm to solve and I think you will get an answer.
