affecting their demand, consumers will purchase more mink coats
d) if more mink coats are purchased this month than last month, it is because the price of
mink coats has fallen
2) A demand curve specifies quantity demanded:
a) over an interval of time
b) only if there is an adequate supply
c) that people would like to be able to buy
d) that people can afford to buy
3) A decrease in the quantity demanded:
a) shifts the demand curve to the left
b) shifts the demand curve to the right
c) is a movement down along the demand curve
d) is a movement up along the demand curve
4) If skiing at Banff and skiing at Whistler are substitutes, an increase in the price of skiing at
Banff will:

increases
