Answer:
Total credit hours a student have = 2.5 hours.
Step-by-step explanation:
P.S - The exact question is -
Given - 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.
To find - How many credit hours will a student have to take for the two tuition costs to be equal.
Proof -
If the two tuition cost are equal, then
C(h) = S(h)
⇒250 + 200h = 300 + 180h
⇒200h - 180h = 300 - 250
⇒20h = 50
⇒2h = 5
⇒h =
⇒h = 2.5
∴ we get
Total credit hours a student have = 2.5 hours.
