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)

Ithink it may be 10^3,that mean 10 'exponent ^3 would the population scientific in terms to evaluate by such and
