How much money should be deposited today in an account that earns 8.5% compounded monthly so that it will accumulate to 8000 in three​ years?

Question

I am having issues solving this. I follow the equation and everything and still manage to get the answers wrong.

Answer 1

A = P(1 + r/n)^nt

8,000 = P(1 + .085/12)^(12)(3)

8,000 = P(1 + .00708)³⁶

8,000 = P(1.00708)³⁶

8,000 = P(1.28930)

$6204.91 = P
