Answer 1

Answer:

The answer is below

Explanation:

The graph is attached below.

a) The price elasticity of demand is given by:

price elasticity of demand = $\frac{\%\ change\ in\ quantity }{\%\ change\ in\ price}=\frac{\Delta Q}{\Delta P}$

$\Delta Q=\frac{Q_2-Q_1}{(Q_2+Q_1)/2} \\\\\Delta P=\frac{P_2-P_1}{(P_2+P_1)/2}$

Price of elasticity demand =   $\frac{\frac{Q_2-Q_1}{(Q_2+Q_1)/2} }{\frac{P_2-P_1}{(P_2+P_1)/2} }$

Price of elasticity demand =   $\frac{\frac{50-100}{(50+100)/2} }{\frac{4.5-4}{(4.5+4.0)/2} }=\frac{-0.6667}{0.1176} =5.7$

Since the price of elasticity demand > 1, it is elastic

b) Price of elasticity demand =   $\frac{\frac{200-300}{(200+300)/2} }{\frac{3-2}{(3+2)/2} }=\frac{-0.4}{0.4} =1$

Since the price of elasticity demand = 1, it is unitary

c) Price of elasticity demand =   $\frac{\frac{400-450}{(400+450)/2} }{\frac{1-0.5}{(1+0.5)/2} }=\frac{-0.1176}{0.6667} =0.18$

Since the price of elasticity demand < 1, it is inelastic
