In a schedule of 7 classes. Ella has 2 elective classes. What is the ratio of elective to non-elective classes in Ella's schedule?

The tuition costs, c, for a local community college are modeled by c(h) = 250 + 200h, where h represents the number of credit hours taken. the local state university has tuition costs, s, modeled by the function s(h) = 300 + 180h. how many credit hours will a student have to take for the two tuition costs to be equal? round the answer to the nearest tenth of an hour.

9/10 divide by -3/15 as a mixed number

If you answer 2+2 you will get over 80 points
