Final answer:
Without the number of Starbucks stores from the previous year, it is impossible to calculate the percentage growth of stores in China in 2021.
Step-by-step explanation:
To calculate the percentage growth of Starbucks stores in China compared to the previous year, we would need the number of stores from the previous year.
However, since the question does not provide that information, we cannot compute the exact percentage growth.
Typically, you would find the difference in the number of stores between the two years, divide that by the number from the previous year, and then multiply by 100 to get the percentage increase.
Therefore, without the previous year's data, the percentage growth cannot be determined from the information given.
