Material A costs $3 per kilogram, and material B costs$5 per kilogram. If 10 kilograms
of material K consists of x kilograms of material A and y kilograms of material B, is x >
y?
(1) y > 4

I tend to start with the equality to see if it works or on which side it will fall. So A = 5 and B = 5. => (5*5) + (3*5) = 25 + 15 = 40. So if they are equal it will be$40. The only way to get it to be <$40 is to have more B than A. So we have enough to solve.

You need less money so you need more of the cheaper fabric. So you need more A than B. Same result though. Really solving it is not necessary, once you see that you have a relation to the dollar amount in which you can create an inequality you are golden.
