Answer

60 $,$ Q_A = 20$

Here are the solutions to the questions.

Question One A: Price Elasticity of Demand

Given points: Point A: $P_A = 60$ , $Q_A = 20$ Point B: $P_B = 15$ , $Q_B = 40$

I. The price elasticity of demand at point A (Point Elasticity)

Step 1: Calculate the change in quantity ( $\Delta Q$ ) and change in price ( $\Delta P$ ) between the two points. $\Delta Q = Q_B - Q_A = 40 - 20 = 20$

The price elasticity of demand at point A (Point Elasticity) Step 1: Calculate the change in quantity ( Q) and change in price ( P) between the two points. Q = Q_B - Q_A = 40 - 20 = 20 P = P_B - P_A = 15 - 60 = -45
