A donut shop sells fresh baked donuts from 5 a.m. until 3 p.m. every day but Sunday. The cost of making and selling a dozen glazed donuts is $2.00. Since this shop does not sell day-old donuts the next day, what should the manager do if she still has ten dozen left at 2:30 p.m.?

a.	lower the price of the remaining donuts even if the price falls below $2.00
b.	lower the price of the remaining donuts as long as it's more than $2.00
c.	lower the price on all donuts so they will all be sold earlier in the day
d.	throw them away and produce ten fewer dozen tomorrow
