Suppose that a fashion company determines that the cost, in dollars, of producing x cellphone cases is given by C(x)equalsneg

Semenov [28]

Answer:

(a)$29.95

(b)A

Step-by-step explanation:

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

$C(x)=-0.05 x^2+55 x.$

We are required to evaluate: $\dfrac{C(251)-C(250)}{251-250}$

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

$\dfrac{C(251)-C(250)}{251-250}=\$29.95$

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