Homework Help: Reflection Problem

  1. Apr 11, 2008 #1
    1. The problem statement, all variables and given/known data
    A magnifying glass has a converging lens of focal length 17.0 cm. At what distance from a nickel should you hold this lens to get an image with a magnification of +2.00?

    2. Relevant equations

    3. The attempt at a solution

    I did not know how to even start this because the distance of the image is not given so i cannot solve and plug. Please help, just started this lesson couple of days ago. Thanks!
