Answer:
Following the formula [tex]E= ΔX/ΔY[/tex]
where ΔX= changes in the quantity of berths
and ΔY= changes in the price of fuel
The result is that after a 4% increase in the price of fuel, the quantity of berths will decrease in 8.6%.
Explanation:
Cross-Price Elasticity is the result of the division between the porcentual changes in quantity of the good X (in this case berths) against porcentual changes in the price of good Y (in this case the price of fuel). In this case they are complementary goods, and an increase in one will decrease the quantity of the other.
