In a class of 25 students, students were asked if they like French fries, burgers, or neither. 15 students said they like French fries and 10 said they like burgers, with these statistics including the responses of 6 students who said they like both French fries and burgers. How many students do not like either food?
There are 15 - 6 = <<15-6=9>>9 students who like French fries only.
There are 10 - 6 = <<10-6=4>>4 students who like burgers only.
So, 9 + 4 + 6 = <<9+4+6=19>>19 students like either French fries, burgers, or both.
Hence, 25 - 19 = <<25-19=6>>6 students do not like either fries or burgers.
