Scenario 51
Suppose that when the average college student’s income is $10,000 per year, the annual
quantity demanded of Patty’s Pizza is 50 and the annual quantity demanded of Sue’s
Subs is 80. Suppose that when the price of Patty’s Pizza increases from $8 to $10 per
pie, the quantity demanded of Sue’s Subs increases from 80 to 100. Suppose also that
when the average student’s income increases to $12,000 per year, the annual quantity
demanded of Patty’s Pizza increases from 50 to 60.
