First let's calculate the profit in the deal, subtracting the market value and the selling value:

So the profit is $55,000.
Now, calculating the fee of 10% of the profit, we have:

So the fee is $5,500, therefore the correct option is the fourth one.
Question is not complete and so I have attached the complete question.
Answer:
C: f(x) = -½x + 4
Step-by-step explanation:
Using slope formula between 2 points, we know that;
slope; m = (y2 - y1)/(x2 - x1)
Let's consider 2 points from the table;
(0, 4) and (-4, 6)
Thus;
m = (6 - 4)/(-4 - 0)
m = 2/-4
m = -½
Now using slope intercept form equation which is y - y1 = m(x - x1), we can find the equation of the function by picking on point say (0, 4).
Thus;
y - 4 = -½(x - 0)
y - 4 = -½x
y = -½x + 4
Thus;
f(x) = -½x + 4
Multiply the 12 by three and get 36. Then divide that by four and get 9
