Baldo: I'm worried about my math class. Baldo: Our math teacher polled the class... Baldo: 40 percent said they were good with numbers... Baldo: And 75 percent said they weren't.
@TEMPLO S.U.D.You seem to be part of the 75% who have a problem with numbers. 40+75=115. That means the teacher either has 15% more students or a couple of students were polled twice.
