Investing math problem!

  1. Nov 22, 2006 #1
    How many years (to two decimal places) will it take $5,000 to grow to $7,500 if invested at 8% compounded semiannually? Compounded continuously? Thank you!

    Plug into&chug out of the formula given in your textbook.

    simple interest; A=P(1+rt)
    compound interest; A=P(1+r/m)^mt
    continuous compound interest; A=Pe^rt

    I just can't seem to get my answer to match what is in the textbook. :(

    You haven't shown us what you did, you haven't told us what answer you got, you haven't told us what the answer in the book was! I don't see how we can help you!
