Solution:
Based on the information provided:- 80% of people enjoy vanilla flavor.- 25% enjoy both vanilla and cherry flavor.To find out what percentage of vanilla enjoyers also enjoy cherry, we need to calculate the ratio of people who enjoy both flavors to those who enjoy vanilla. In other words, we need to divide the percentage of people who enjoy both flavors by the percentage of people who just enjoy vanilla, then multiply by 100 to convert it to a percentage.$$ \frac{25}{80} \times 100 = 31.25% $$So, 31.25% of the people who enjoy vanilla flavor also enjoy cherry flavor.
