Investigate how demand elastiticities are affected by increases in demand. Shift each of the demand curves in Figures a, b, and c to the right by 10 units. For example, point a in Figure a would shift rightward from location (10 units, $2) to (20 units, $2), while point bwould shift rightward from location (40 units, $1) to (50 units, $1). After making these shifts, apply the midpoint formula to calculate the demand elasticities for the shifted points.
