For each scenario, calculate the cross-price elasticity between the two goods and identify how the goods are related. Please use the midpoint method when applicable, and specify answers to one decimal place.

A 20%20% price increase for Product A causes a 10%10% decrease in its quantity demanded, but no change in the quantity demanded for Product B.

cross-price elasticity between A and B:

relationship between A and B:

Product C increases in price from $3$3 a pound to $4$4 a pound. This causes the quantity demanded for Product D to increase from 4444 units to 8585 units.

cross-price elasticity between C and D:

relationship between C and D:

When the price of Product E decreases 9%9%, this causes its quantity demanded to increase by 14%14% and the quantity demanded for Product F to increase 12%12%.

cross-price elasticity between E and F:

relationship between E and F:
