Answer:
$4125
Step-by-step explanation:
Let 'a' represent the additional income Mrs. King must earn. In order for her disposable income to remain the same, we must have ...
(66000 +a)(1 -0.20) = 66000(1 -0.15)
66000 +a = 66000(0.85/0.80) = 66000(1 +0.05/0.80)
a = 66000(5/80) = 4125
Mrs King must earn $4125 more before tax to maintain her after-tax income.
4 x 4
-------- = ---------- - ---
x - 4 x - 4 3
multiply through by 3(x-4):-
12 = 3x - 4(x-4)
12 = 3x - 4x + 16
--4 = -x
x = 4
What do we get if we substitute 4 for x in the original equation?
