In the short growing season of the Canadian arctic territory of Nunavut, some gardners find it possible to grow gigantic cabbages in the midnight sun.

Assume that the final size of a cabbage is proportional to the amount of nutrients it receives, and inversely proportional to the number of other cabbages surrounding it.

A cabbage that received 20 oz. of nutrients and had 12 other cabbages around it grew to 30 lb. What size would it grow to if it had received 10 oz. of nutrients and had only 5 cabbage “neighbors”?
