There are 18 bikes in a bike rack. there are 4 more blue bikes then yellow bikes , and 2 less yellow bikes than green bikes. how many bikes of each color are in the rack ?

If i think this is what your asking, he should look at the grams or pounds/ounces and compare the to their cost then max can identify which one is proportional and which is not ( i think xd)
