Answer:
a) the equilibrium price may rise or fall but the equilibrium quantity will rise for certain.
Explanation:
For the price there are two forces pushing:
one that the increase in caffeinated beverages prices which requires coffee beans as input increases will make possible to pay more for the coffee beans
But also as the production can increase due to the increase in technology it may be cheaper to produce the coffee bean, pushing the price down.
The net effect of this with no more calculaton is uncertain.
What is clear is that because the product which the coffee eans price increases, there will be more demand for themand will ebe possible to meet it as there is also an icnrease in productivity. This makes the quantity of equilibrium clearly going up.
