TammisaurusRex Group Title

"After 6 years, what is the total amount of a compound interest investment of $35,000 at 4% interest, compounded quarterly?" I tried to solve this question and I thought I did it right but my answer matched none of the multiple-choice answers I was given, so apparently I did something wrong.

    I think the formula I'm supposed to use is the Compound Interest Formula: \[A = P(1 + \frac{ r }{ n })^{nt}\] Where A = total, P = principal, t = time (years), r = annual interest rate, and n = number of compounds per year

    But every time I plug the values in I get 89,000 something, but my choices are as follows: A. $37,153.21 B. $39,438.88 C. $44,440.71 D. $56,295.30

    Oh wait!! I realize what I did wrong! Instead of plugging in r/n inside the parenthesis, I only plugged in r.

    my idea was you didnt convert 4% correctly as .04 ... but that was just a guess
