Answer:
[tex]C(n) = 435n + 150[/tex]
Step-by-step explanation:
Given
[tex]Base = 400[/tex] -- Base charge per month
[tex]Utilities = 150[/tex]
[tex]Adverts = 35[/tex] per month
Required
The cost function
To do this, we multiply the rates by the number of months.
So, we have:
[tex]C(n) = Base * n + Adverts * n + Utilities[/tex]
So, we have:
[tex]C(n) = 400 * n + 35 * n + 150[/tex]
[tex]C(n) = 400n + 35n + 150[/tex]
[tex]C(n) = 435n + 150[/tex]
