7. (SSEMI2d) Last week, the number of individuals willing and able to purchase a new Ford Sport Utility Vehicle
increased. The same week, the number of sellers willing and able to sell new Ford SUVS dropped. This week, the
opposite has happened: the quantity of SUVs demanded has fallen, but the quantity of SUVS supplied has risen.
What would account for all of these changes?
a) individuals acting as demanders
b) prices acting as incentives
c) quantities acting as barriers
d) businesses acting as suppliers
