The average cost per unit C(x), in dollars, to produce x units of toy cars is given by C(x)=(8000)/(x−50)C(x)=(8000)/(x−50). Wha

podryga [215]

$C(x)= \frac{8000}{x-50}$

gives an average cost per unit, if we want to produce x of them.

So for example, we want to produce 500 toy cars for our store, and we need a price per unit (per 1 toy car). What we do is we calculate C(500).

So to calculate the cost of one unit when producing 1250, we calculate C(1250)

$C(1250)= \frac{8000}{1250-50}= \frac{8000}{1200}=6.67$ $ is the cost of 1 toy car.
