This is a simple algebra equation:
Net Income = Earnings - ITDA (interest/taxes/depreciation & amortization)
so fill in what we know
7,5000,000 Earnings
2,100,000 Net Income
2,000,000 interest
(7,5000,000) * 30% Taxes
? for DA
so:
2,1000,000= 7,500,000 - 2,100,000-(7,500,000*.30) - X
You would then solve for X
2,100,000 = 3,150,000 - X
X= 1,050,000 Depreciation and Amortization
