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. If consumers decide that they want 20 percent fewer weezils at every price, the equation for the new demand curve for weezils will be __________.Qd = 20 - 1.6P Qd = 0.2(20 - 2P) Qd = 0.8(20 - 2P) Qd = 80(20 - 2P)
