This viseo goes through the solution to a viewer-submitted practice problem. The problem goes as follows: I've been given the equation for the quantity demanded and the quantity supplied. The simplified versions look like this: Qd = 400 - 4p Qs = -200 + 6p The Equilibrium Price is 60 and the Quantity demanded is 160. In order to get the PED, should I replace the "p" in the equation for the quantity demanded for a random number, lets say, 50, and see how much the QD changes?
