Not all advertisers pay the same. Some pay less, some pay more. As you they are trying to make the most of their advertising budget. If their keywords convert to a high degree, they will naturally pay more. If not, they will pay less.
This fluctuations happens.. Theres nothing to worry about. As JohnS0N said, Not all the advertisers pay same CPC.
