(2) 38.2% because 26+42=68 and 26/68=0.382

Approximately 38.2% of people who preferred burgers in Jenna's senior class survey were female. Therefore, the correct answer is (2) 38.2.

To find the percentage of people who preferred burgers and were female, divide the number of females who preferred burgers by the total number of people who preferred burgers and then multiply by 100.


\[ \text{Percentage} = \left( \frac{\text{Females who preferred burgers}}{\text{Total who preferred burgers}} \right) * 100 \]\[ \text{Percentage} = \left( (26)/(42 + 26) \right) * 100 \]\[ \text{Percentage} = \left( (26)/(68) \right) * 100 \]\[ \text{Percentage} \approx 38.24 \]

So, the answer is approximately 38.2. Therefore, the correct option is (2) 38.2.
