Answer:
the cross price elasticity of demand is -1.44
Explanation:
The computation of the cross price elasticity of demand is shown below:
= Percentage change in quantity demanded Ă· Percentage change in price
where
Percentage change in quantity demanded is
= (Q2 - Q1) Ă· (Q2 + Q1) Ă· 2
= (24 - 30) Ă· (24 + 30) Ă· 2
= -6 Ă· 27
= -0.2222
And, the percentage change in price is
= (P2 - P1) Ă· (P2 + P1) Ă· 2
= ($3.50 - $3) Ă· ($3.50 + $3) Ă· 2
= $0.50 Ă· $3.25
= 0.1538
So, the cross price elasticity of demand is -1.44
