The weekly profits of a Company A is determined by multiplying the number of units sold by the cost per unit. The company sold 2000 units one week at a price of $10 per unit. For each $5 increase in cost per unit, the company sells 10 fewer units.

The weekly profits of Company B is represented by y.

What quadratic inequality represents a week where the profits of Company B is less than Company A?

y<−50x2+9900x+20,000 y less than negative 50 x squared plus 9900 x plus 20,000

y≤−50x2+19950x+20,000 y less than or equal to negative 50 x squared plus 19950 x plus 20,000

y≤−50x2+9900x+20,000 y less than or equal to negative 50 x squared plus 9900 x plus 20,000

y<−50x2+19950x+20,000 y less than negative 50 x squared plus 19950 x plus 20,000
