Which would be the correct sequence of events in the speedboat industry if waterway access was improved and, at the same time, a lighter polymer became available that increased production efficiency? A. Supply would shift right, demand would shift left, equilibrium price would increase, and equilibrium quantity would be indeterminable. B. Supply would shift right, demand would shift right, equilibrium price would be indeterminable, and equilibrium quantity would increase. C. Supply would shift left, demand would shift right, equilibrium price would decrease, and equilibrium quantity would increase. D. Supply would shift left, demand would shift left, equilibrium price would be indeterminable, and equilibrium quantity would decrease.

Answer: The correct answer is "Supply would shift right, demand would shift right, equilibrium price would be indeterminable, and equilibrium quantity would increase.".

Explanation: The correct sequence of eventis in the speedboat industry if waterway access was improved and, at the same time a lighter polymer became available that increased production efficiency would be: Supply would shift right, demand would shift right, equilibrium price would be indeterminable, and equilibrium quantity would increase.

By improving access to the waterway, there would undoubtedly be an increase in the demand for speedboats, as a result it would shift to the right.

The increase in production efficiency, translates into an increase in supply, therefore the offer would also shift to the right.
