The chess club has 50 members. they want to raise $680 for a trip to a competition. the school will give $130 how much must each member pat

So what they need to rais is what the school doesn't give them
so to find that subtract what the school gives them from how much they need
need=680
given=130
680-130=550
they need to raise 550

if each member raises the same amount we fid that by doing
total divided by number of members
total=550
number o fmembers=50
550/50=11
each must raise $11
