Exhibit 4-1
The following are the equations for the supply and demand curves in the market for
weezils:
Demand: Qd = 20 − 2P
Supply: Qs = 5 + 3P
where Qd is the quantity demanded, Qs is the quantity supplied, and P is the price per
weezil in dollars
Refer to Exhibit 4-1. If consumers decide that they want 20 percent fewer weezils at
every price, the equation for the new demand curve for weezils will be
a. Qd = 20 − 1.6P.
b. Qd = 0.2(20 − 2P).
c. Qd = 0.8(20 − 2P).
d. Qd = 80(20 − 2P).
