A bagel shop sells fresh baked bagels from 5 a.m. until 7 p.m. every day. The shop does
not sell dayold bagels, so all unsold bagels are thrown away at 7 p.m. each day. The

throwing bagels away. If the manager has 8 dozen bagels left at 6:30 p.m. on a
particular day, which of the following alternatives is most attractive?

dozen.
b. Lower the price of the remaining bagels, but under no circumstances should the price
fall below $1.00 per dozen.
c. Throw the bagels away and produce 8 fewer dozen bagels tomorrow.
d. Starting tomorrow, lower the price on all bagels so they will all be sold earlier in the
day.
An increase in quantity supplied

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.

demand for pizza and what does the value indicate about the demand for pizza?
