Answer: ![\$18,629](https://tex.z-dn.net/?f=%5C%2418%2C629)
Step-by-step explanation:
Given
The unit cost is given by
![C(x)=0.6x^2-168x+30,389](https://tex.z-dn.net/?f=C%28x%29%3D0.6x%5E2-168x%2B30%2C389)
find the derivative of the unit cost and equate it to zero to obtain the minimum value
![C'(x)=0.6\times 2x-168\\\Rightarrow 0.6\times 2x-168=0\\\Rightarrow 1.2x=168\\\\\Rightarrow x=\dfrac{168}{1.2}\\\\\Rightarrow x=140](https://tex.z-dn.net/?f=C%27%28x%29%3D0.6%5Ctimes%202x-168%5C%5C%5CRightarrow%200.6%5Ctimes%202x-168%3D0%5C%5C%5CRightarrow%201.2x%3D168%5C%5C%5C%5C%5CRightarrow%20x%3D%5Cdfrac%7B168%7D%7B1.2%7D%5C%5C%5C%5C%5CRightarrow%20x%3D140)
Substitute 140 for
in the cost function, we get
![C(140)=0.6[140]^2-168(140)+30,389\\C(140)=11,760-23,520+30,389\\C(140)=\$18,629](https://tex.z-dn.net/?f=C%28140%29%3D0.6%5B140%5D%5E2-168%28140%29%2B30%2C389%5C%5CC%28140%29%3D11%2C760-23%2C520%2B30%2C389%5C%5CC%28140%29%3D%5C%2418%2C629)
