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. 250 + 200h = 300 + 180h 250 + 200h = 300 + 180h − 180h − 180h 250 + 20h = 300 h = credit hours

To solve how many credit hours will a student have to take for the two tuition costs to be equal, the two functions should be equated and solve for the number of hours
C (h) = S (h)
250 + 200h = 300 + 180h
200h – 180h = 300 – 250
20h = 50
H = 2.5 credit hours

The required equation is: [tex]\mathbf{150 + 200h = 300 + 180h}[/tex] and the number of credit hours is 7.5

The functions are given as:

[tex]\mathbf{C(h) = 250 + 200h}[/tex]

[tex]\mathbf{S(h) = 300 + 180h}[/tex]

When the two tuition costs are equal, we have:

[tex]\mathbf{C(h) = S(h)}[/tex]

This gives

[tex]\mathbf{150 + 200h = 300 + 180h}[/tex]

Collect like terms

[tex]\mathbf{ 200h -180h= 300 -150 }[/tex]

[tex]\mathbf{ 20h= 150 }[/tex]

Divide both sides by 20

[tex]\mathbf{ h= 7.5 }[/tex]

Hence, the required equation is: [tex]\mathbf{150 + 200h = 300 + 180h}[/tex] and the number of credit hours is 7.5
