It represents the average cost of producing 251 items.

Answer :

Answer:

(a)$29.95

(b)A

Step-by-step explanation:

The​ cost, in​ dollars, of producing x cellphone cases is given by:

[tex]C(x)=-0.05 x^2+55 x.[/tex]

We are required to evaluate: [tex]\dfrac{C(251)-C(250)}{251-250}[/tex]

[tex]C(251)=-0.05(251)^2+55(251)=10654.95\\C(250)=-0.05(250)^2+55(250)=10625\\\text{Therefore:}\\\\\dfrac{10654.95-10625}{251-250}=29.95[/tex]

[tex]\dfrac{C(251)-C(250)}{251-250}=\$29.95[/tex]

The value calculated above represents the additional cost to produce one more item after making 250 items.
