21) suppose that in the clothing market, production costs have fallen, but the
equilibrium price and quantity purchased have both increased. based on this
information we can conclude that:
a.the supply of clothing has grown faster than the demand for clothing.
b.demand for clothing has grown faster than the supply of clothing.

d.there is no way to determine what has happened to supply and demand with this

22) assume a pure monopolist is currently operating at a price-quantity combination on
the inelastic segment of its demand curve. if the monopolist is seeking maximum
profits, it should:
a.retain its current price-quantity combination.
b.increase both price and quantity sold.
c.charge a lower price.
d.charge a higher price.
23) when a pure monopolist is producing its profit -maximizing output, price will:
a.be less than mr
b.equal neither mc nor mr
c.equal mr
d.equal mc
