B.2.5 to 3.0 percent, which is higher than that of most other industrial countries.
C.4.5 to 5.0 percent, which is lower than that of most other industrial countries.

9) the demand for commodity x is represented by the equation p = 10 – 0.2q and supply
by the equation p = 2 + 0.2q.
refer to the above information. if demand changed from p = 10 – .2q to p = 7 – .3q, we
can conclude that:
a.demand has increased.
b.demand has decreased.
c.supply will increase.
d.supply will decrease.
10) if production is occurring where marginal cost exceeds price, the purely competitive
firm will:
a.maximize profit, but resources will be underallocated to the product.
b.maximize profit, but resources will be overallocated to the product.
c.fail to maximize profit and resources will be overallocated to the product.
d.fail to maximize profit and resources will be underallocated to the product.
11) when compact disc (cd) players first came on the market, they sold for over $1,000.
now they cost only $100. these facts imply that:
a.the cd industry was once competitive, but is now monopolistic.
b.fewer firms produce cd players than was the case five or ten years ago.
c.the demand curve for cd players has shifted leftward.
d.the cd player industry is a decreasing-cost industry.
