Solution and Explanation:
Net income = $23000 , Interest expense = $5000 , Tax rate = 35%
Notes payable = $24000 , Longterm debt = $75000 , Common equity = $260000
ROE = Net income divided by Common equity = 23000 divided by 260000 = 0.088 = 8.8%
Net income before Tax =
=

= 35384.615
EBIT = Net income before tax + Interest
= 35384.615 + 5000 = 40384.615
Invested capital = Notes payable + Longterm debt + Common equity
= 359000
ROIC = EBIT * (1- Tax rate )/ Invested capital

= 0.0731% = 7.31 % (rounded off)
