Answer:
Option (A) is correct.
Step-by-step explanation:
Return on investment = (operating profit ÷ Invested capital) × 100
= ($171 million ÷ $610 million) × 100
= 0.28 × 100
= 28%
Residual income:
= operating profit - (Invested capital × Imputed interest rate)
= $171 - ($610 ×20%)
= $171 - $122
= $49 million
Therefore, Trailer’s return on investment (ROI) and residual income is 28% and $49 million, respectively.
