Answer:
|x - 145000| = 1500
Explanation:
The salary is x which is 145000.
The variation is $1500.
That means the salary could be as low as 145000 - 1500 and as high as 145000 + 1500.
x = 145000 - 1500 or x = 145000 + 1500
Subtract 145000 from both sides of both equations.
x - 145000 = -1500 or x - 145000 = 1500
Change to an absolute value equation.
**************************************************************
Recall that to solve an absolute value equation of the form |X| = k, where X is an expression in x and k is a number, you change the absolute value equation into the equation: X = -k or X = k.
***************************************************************
Now we do the reverse of the step shown above in the "Recall" section. We have the equation, and we want the absolute value equation.
x - 145000 = -1500 or x - 145000 = 1500
|x - 145000| = 1500
