The problem of confusion is $ and cent and g or kg. But not for the guys who passed the primary education. So the first thing first, is to transform g to kg and cent to $ which is 0.86kg and $0.60. Now we know that the cost per kg of the large size is 3.15/3= $1.05, but for the regular size is .60/.86 or $0.70. So which one would you buy?
