Answer:
$0
Step-by-step explanation:
Not-for-profit organizations are required to record donations, e.g. money, food, clothes, etc., but they are not required to record voluntary work. In this case, Chris was a volunteer who spent 240 hours caring for turtles. It doesn't matter how much does Chris earns in his normal job, he cannot deduct volunteer work and the Turtle Society does not need to record his work either.
