The Net Income For Blue Bird LTD. is $69362.
Explanation:
As per Accounting Equation;
Total Asset = total equity + total liabilities
as we are don't have equity so we will take it as x and liabilities as y
Now our equation will be,
$223500 = x+y ........................................................................(i) equation
we are also given a debt equity ratio = 
Debt Equity Ratio =
.45x = y................................................... (ii) equation
so now putting y of (ii) equation into (i) equation, we will get
$223500 = x+ .45x
x =
x (i.e equity) = $154,138
and, y (debt ) = $69362
to find net income , where Return on equity (ROE) =
net income = .12×$154138
net income = $18497
