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 รท Percentage change in price
where
Percentage change in quantity demanded is
= (Q2 - Q1) รท (Q2 + Q1) รท 2
= (24 - 30) รท (24 + 30) รท 2
= -6 รท 27
= -0.2222
And, the percentage change in price is
= (P2 - P1) รท (P2 + P1) รท 2
= ($3.50 - $3) รท ($3.50 + $3) รท 2
= $0.50 รท $3.25
= 0.1538
So, the cross price elasticity of demand is -1.44
