A 75.0g meter stick initially balances on a fulcrum at the 49.1cm mark. The fulcrum is then moved to the 65.0 cm mark and the following 3 masses are attached to the meter stick at the positions given and the meter stick is balanced. What the is position on the meter stick of Mass 3?

Mass 1 = 50g, position = 75 cm mark

Mass 2 = 20g, position = 15 cm mark

Mass 3 = 55g, position = ?

* posted this question before but it did not show enough work for me to understand the problem * * pls answer clearly with enough work *
