Hillbilly cousins Jethro Bodine and Elly May Clampett are sent out by Granny Moses to fetch possums and mustard greens for the daily vittles. Table 1 gives the number of possums hunted per hour or the number baskets of mustard greens gathered per hour by Cousin Jethro and Cousin Elly May, respectively. For example, an hour worth of chores by Jethro always yields either five possums or three baskets of mustard greens.
