You have the following equation:

|n| = 8 the two vertical bras | | means absolute value of variable n

when you have an equation with an absolute value you consider that n could be negative or positive, because the absolute value of a number always results in a positive number. Then, n can be 8 or -8, because |-8| = |8| = 8. Hence, you have

n = ±8

Answer:

$131,600

Step-by-step explanation:

If the listing price is P, then the net is the difference between that and all of the various costs.

P -(5%×P) -94,000 -16000 = 15,000

0.95P = 125,000

P ≈ 131,600 . . . . . . divide by 0.95

The minimum listing price must be $131,600.
