Answer:no relationship,substitutes and complements
Step-by-step explanation:
A 20% price increase for Product A causes a 10% decrease in its quantity demanded, but no change in the quantity demanded for Product B.
The answer is : Cross-Price Elasticity=0, Relationship=no relationship
Product C increases in price from $1 a pound to $2 a pound. This causes the quantity demanded for product D to increase from 27 units to 81 units.
Answer: Cross price elasticity 81/54=1.5, relationship=substitutes
When the price of Product E decreases 2%, this causes its quantity demanded to increase by 14% and the quantity demanded for Product F to increase 17%.
Answer: Cross-Price elasticity which is = -8.5, relationship= complements
