Question

PLZ help me...
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.

1. 250 + 200h = 300 + 180h
2. 250 + 200h = 300 + 180h over
− 180h − 180h
3. 250 + 20h = 300

h=____________ credit hours

Answer 1

\[ C (h) = S (h)\]\[250 + 200h = 300 + 180h\]\[200h – 180h = 300 – 250\]\[20h = 50\]
Does that help?

Answer 2

yeah, thx

Answer 3

Ok Np.

Answer 4

1. 250 + 200h = 300 + 180h
2. 250 + 200h = 300 + 180h over
− 180h − 180h
3. 250 + 20h = 300
so 250+20 =70 so i belive you round 70 to the nearest 10 hope this helps
