Can someone help me plsls

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.

Just tell me how to set up the equation.

Check all that apply. f is a function. f is a one-to-one function. c is a function. c is a one-to-one function.
