Once a week, Smith purchases a six-pack of cola and puts it in his refrigerator for his two children. He invariably discovers that all 6 cans are gone on the first day. Jones also purchases a six-pack of cola once a week for his two children, but unlike Smith, he tells them that each may drink no more than three cans.

Thus, the cost of drinking a cola is
lower at smiths house than at jones

You and your friend Joe have identical tastes. At 2 p.m., you go to the local Ticketmaster outlet and buy a $30 ticket to a basketball game to be played that night in Syracuse, 50 miles north of your home in Ithaca.
