Answer:
B. 0.71, and they are substitutes
Explanation:
The computation of the cross- price elasticity of demand is shown below:
= (change in quantity demanded ÷ average of quantity demanded) ÷ (percentage change in price ÷ average of price)
where,
Change in quantity demanded is
= Q2 - Q1
= 4 - 3
= 1
And, average of quantity demanded is
= (4 + 3) ÷ 2
= 3.5 0.2857
Change in price is
= P2 - P1
= $3 - $2
= $1
And, average of price is
= ($3 + $2) ÷ 2
= 2.5
So, after solving this, the cross price elasticity of demand is +0.7 and it refers to the substitutes goods
