I NEED HELP PLEASE, THANKS! :)

Answer 1

Answer:

  2444

Step-by-step explanation:

The total cost is the integral of the marginal cost.

  $\displaystyle C=\int_{144}^{625}{\dfrac{94}{\sqrt{x}}}\,dx=\left. 2\cdot 94\sqrt{x}\right|_{144}^{625}=188(25 -12)=\boxed{2444}$

The total cost of producing units 144 through 625 is 2444.
