The linear function that models the situation is given by:
[tex]C(p) = 100 + 12p[/tex]
------------------------
A linear function for the cost C of taking care of p puppies has the following format:
[tex]C(p) = C(0) + ap[/tex]
In which:
------------------------
[tex]a = \frac{220 - 172}{10 - 6} = 12[/tex]
Thus:
[tex]C(p) = C(0) + 12p[/tex]
------------------------
The cost of $172 with 6 puppies means that when p = 6, C = 172, and we use this to find C(0).
[tex]C(p) = C(0) + 12p[/tex]
[tex]172 = C(0) + 12(6)[/tex]
[tex]C(0) = 172 - 72[/tex]
[tex]C(0) = 100[/tex]
Thus, the linear model is:
[tex]C(p) = 100 + 12p[/tex]
