The table shows the demand schedule for a particular product.
Refer to Table 17-9. Suppose the market for this product is served by two firms that
have formed a cartel. If the marginal cost of production is $0 and there is no fixed cost,
the combined profit of the cartel will be
a.$16
b.$24
c.$30
d.$32
2) Market failure can be caused by
a.too much competition.
b.externalities.
c.low consumer demand.
d.scarcity.

6) Assume that Zimbabwe and Portugal can switch between producing toothbrushes and
producing hairbrushes at a constant rate.
Assume that Zimbabwe and Portugal each has 60 machine minutes available.
Originally, each country divided its time equally between the production of
toothbrushes and hairbrushes. Now, each country spends all its time producing the good
in which it has a comparative advantage. As a result, the total output increased by
a.4 toothbrushes and 2 hairbrushes.
b.10 toothbrushes and 5 hairbrushes.
c.16 toothbrushes and 8 hairbrushes.
d.20 toothbrushes and 10 hairbrushes.

14) Table 17-31
Imagine a small town in a remote area where only two residents, Maria and Miguel,
own dairies that produce milk that is safe to drink. Each week Maria and Miguel work
together to decide how many gallons of milk to produce. They bring milk to town and
sell it at whatever price the market will bear. To keep things simple, suppose that Maria
and Miguel can produce as much milk as they want without cost so that the marginal
cost is zero. The weekly town demand schedule and total revenue schedule for milk is
shown in the table below:
