    Given:

    2008 - 40 giant turtles tagged

    2009 - 50 turtles capture where 16 were tagged

    2010 - 30 turtles capture where 8 were tagged

    2009:

    40/x = 16/50

    40*50 = 16x

    2000 = 16x

    2000/16 = x

    125 = x

    2010:

    40/x = 8/30

    40*30 = 8x

    1200 = 8x

    1200/8 = x

    150 = x
