Answer:

$\boxed{\mathrm{Option \ C}}$

Step-by-step explanation:

=> $x^2+22x = 31$

=> $(x)^2+2(x)(11) = 31$

Since b = 11 , So $(11)^2$ needs to be added to both sides

Adding $(11)^2$ to both sides

=> $(x)^2+2(x)(11)+(11)^2 = 31+(11)^2$

Completing the square

=> $(x+11)^2 = 31+121$

=> $(x+11)^2 = 152$

2400 + 100x = 2200 + 120x
2400 - 2200 = 120x - 100x
200 = 20x
200/20 = x
10 = x <== they would have to sell 10 systems
