Suppose Table 4.2 (page 89) describes Madeline's preference ranking over slices of cheese pizza and scoops of frozen yogurt. Assume her income is $6 per day, pizza costs $2 per slice, and yogurt costs $2 per scoop. Which alternatives in the table are affordable? Which one will she choose? What if yogurt costs $4 per slice? $6 per slice? Each of these choices corresponds to a point on her demand curve for soup; plot them.
