A company’s total cost from manufacturing and selling x units of their product is given by: y = 2x2 – 600x + 49,000. How many un

ale4655 [162]

Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

$y=2x^2-600x+49000$

We need to find the number of units in order to minimize cost.

We first derivative w.r.t. x,

$y'=4x-600$

For critical points:

$y'=0\\\\4x-600=0\\\\4x=600\\\\x=\dfrac{600}{4}\\\\x=150$

Now, we will check whether it is minimum or not.

We will find second derivative .

$y''=4>0$

So, it will yield minimum cost.

Minimum cost would be

$y(150)=2(150)^2-600\times 150+49000\\\\y(150)=\$4000$

Hence, At 150 units, minimum cost = $4000

Therefore, Option 'c' is correct.
