The price of a pack of Pokemon cards is $5, and the price of a pack of baseball cards is $3. Suppose Will, whose preferences are rational, monotonic, and convex, uses all of his income to buy 5 packs of Pokemon cards and 5 packs of baseball cards.

Will could increase his utility by buying more Pokemon cards and fewer baseball cards O Will could increase his utility by buying more baseball cards and fewer Pokemon cards O Will could increase his utility by buying fewer Pokemon cards and fewer baseball cards O Will is already at his utility maximizing bundle O None of the above
