Algebra story problem

darren · Feb 7, 2011

Giant Gym charges a registration fee on $50 plus a monthly fee of $20. Johnny's Gym charges $75 to join, but only $18 a month. After how many months do they cost the same? I don't know how to figure this problem out. Please help. Thanks

So name your unknown.

Let the # of month = M
