What percentage of respondents chose flavor X the second time, given that 80% of those who picked X the first time chose it again?

To determine the percentage of respondents who chose flavor X the second time based on the information provided, consider the following reasoning:

Assume that there was a total of 100 respondents in the survey for simplicity. If 80% of these respondents chose flavor X the first time, that means 80 individuals selected flavor X initially. According to the information given, 80% of those who chose X the first time chose it again. Therefore, we calculate 80% of the 80 respondents:

0.8 * 80 = 64.

This calculation shows that 64 out of the initial 100 respondents chose flavor X again the second time. Thus, the percentage of respondents who chose flavor X a second time is:

(64/100) * 100% = 64%.

This concludes that 64% of the respondents chose flavor X the second time, making it the correct answer.
