Community college math?

Depends on the college, years of experience, if she is full-time or part time, and the level of education that the instructor has.

Starting out, community college teachers make very little money, despite having a Masters degree on hand. With years of experience, they slide up the salary scale. If they begin pursuing a Ph.D., then once again, they make more money. However, they do make less than their counterparts at universities. A CC instructor with a Ph.D. and 20 years of experience will not make as much as the Tenured professor down the road. But, still more than a high school math teacher.

Most are state employees, so salary scales are available to the public for scrutiny.

The same as any other instructor at a CC. It therefore varies. Lecturers aren't paid much at all, and on a per credit basis, usually a little more than 1k per credit. Tenured professors make a whole lot more, but there are many steps levels so could be anywhere from 50s to 80 k / year, possibly more in high cost of living areas.
