The following system of linear equations is to be solved by SUBSTITUTION. Substituting from the first equation into the second equation produces which new equation? 3(1/2x - 5) - 2y = 3

3x - 2(1/2x - 5) = 3

3x - 2y = 1/2x - 5

y = 1/2(3x - 2y) - 5

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.
