The pipe located underneath Jiro’s kitchen sink was leaking and he did not know how to fix it. He called a plumber who agreed to come fix the leaking pipe in exchange for $125 plus the cost of any parts. The plumber went to Jiro’s home, removed the old pipe that was leaking, and replaced it with a new pipe that the plumber brought with her. When the plumber was finished, she told Jiro that the total cost was $140 and Jiro promptly paid her. Was this a voluntary exchange? Why or why not? A
Yes, because both parties willingly entered the exchange and benefited from it.

B
Yes, because one party exchanged money with another party for a good or service.

C
No, because Jiro was not aware of the final cost before he agreed to the exchange.

D
No, because the plumber’s service was not equal in value to the money paid by Jiro.
