simplifying inequalties
why does 100-(10/6)C >0 simplify to C< (6/10)100 ? My first step was to move the (10/6)C to the other side, to get 100> (10/6)C, but apparently this is wrong..
does the rule of moving stuff to the other side differ when you're using inequalties, as opposed to when your working with equalities?

no you're on the right tracks
you just have to be careful about multiplying by negative numbers

That's fine - you're one step away from having the answer.
One pitfall to avoid with inequalities is multiplying or dividing the whole expression by a negative number, as this will change the sign of the inequality.
