Answer:
16%
Step-by-step explanation:
Given the total number of students in a school = 675
Number of students at a squirrel during flu season = 108
Squirrels are known for transmitting flu disease, therefore if 108 students are at the squirrels during a particular day, there is possibility that this ones have contacted flu.
Percentage of those that have flu = number of students at the squirrels/Total number of students × 100%

= 16%
This means that 16% of the students have flu
