Answer:

<em>For 11.</em>

Lets lay out the equation with the info we have.

v = 7 + 10 x 8

George has opened a new store and he is monitoring its success closely.
LiRa [457]
The correct answer is that the new store will have a profit of $5400 after its fifth month.

Profit is given by subtracting revenue minus cost:
(R-C)(x) = (x²+5x+14)-(x²-4x+5) = x²-x²+5x--4x+14-5 = 5x+4x+14-5=9x+9

Using 5 for x, 
(R-C)(5) = 9(5) + 9 = 45+9 = 54

This is in hundreds of dollars, so it represents $5400.
