A company has determined that its weekly profit is a function of the number of items that it sells. Which equation could

represent the weekly profit in thousands of dollars, y, when the company sells x items?

Oy? -4x2-100

O y-x50x-300

Ox--- 60y-400

07.-8.200

Step-by-step explanation:

Here, the given options are incomplete.

A. y²  = 4 x²  - 100

B. y  = -x² + 50 x - 300

C.  x =  -y² + 60 y - 400

D. x ²  =  - 6 y² + 200

The number of items sold by the company  = x

The profit ( in thousands) is represented as  = y

Now, here as we are looking for the equation representing profit (y)

So, we can disregard the equations which has terms (x)  and ( x²)  in left.

⇒The equations in the options C and D are eliminated.

Similarly, again we are looking for the equation for Profit , not (profit)².

So,we can disregard the equation which has terms (y²)  in left side.

⇒The equation in the options A is eliminated.

Hence, the needed equation representing the profit y is represented in the option B.

B. y  = -x² + 50 x - 300
