Suppose that the number of people attending professional soccer matches rose from 3.40 million to 4.21 million between 2022 and 2023 . Ceteris paribus, these facts imply that the popularity of professional soccer grew by ________%.
The growth in popularity can be calculated as follows:
Growth in popularity = ((Final attendance - Initial attendance) / Initial attendance) * 100%
= ((4.21 million - 3.40 million) / 3.40 million) * 100%
= (0.81 million / 3.40 million) * 100%
= 0.2382 * 100%
= 23.82%
Therefore, the popularity of professional soccer grew by 23.82% between 2022 and 2023.
