Answer and Explanation:
a. The computation of the price elasticity of demand is
i. For business travelers
= {(1900 - 2000) ÷ [(1900 + 2000) ÷2]} ÷ {(250 - 200) ÷ [(200 + 250) ÷ 2]}
= 0.23
ii. For Vacationers
= {(800 - 600) ÷ [(800 + 600) ÷ 2]} ÷ {(250 - 200) ÷ [(200 + 250) ÷ 2]}
= 1.29
b. Since the price would increase from $200 to $250 so the price elastiicy of business travelers & vactationers is 0.23 and 1.29 respectively. So the demand for for airline tickets would be more elastic for vacationers as the business travelers would be less senstitive for price change
