I want to know the answer to the following question:
What percentage of Castille's total earnings was Galicia responsible for?
All the background I'm provided with is that "As a result, from 1480 to 1520 the Kingdom of Galicia contributed more than 10% of the total earnings of the Crown of Castille, including the Americas, well over its economic relevance.". Is that enough to answer the question?
Answer: yes
