Option A: 6x^2+75x+200 is the correct answer

Step-by-step explanation:

The profit is obtained by subtracting the cost from the revenue.

Given

$R(x) = 6x^2+100x+300\\C(x) = 25x+100$

The Profit function will be obtained by subtracting the cost function from the revenue function

So,

$P(x) = R(x) - C(x)\\= (6x^2+100x+300)-(25x+100)\\=6x^2+100x+300-25x-100\\=6x^2+100x-25x+300-100\\P(x)=6x^2+75x+200$

Hence,

Option A: 6x^2+75x+200 is the correct answer
