Final answer:
Using the formula ROE = ROA × (1 + Debt-to-Equity Ratio), Company B's ROE is calculated to be 0.190 after rounding to three decimal places.
Step-by-step explanation:
To calculate the Return on Equity (ROE) for Company B using the provided Return on Assets (ROA) and Debt-to-Equity Ratio, we can use the formula:
ROE = ROA × (1 + Debt-to-Equity Ratio)
Given Company B's ROA is 6.8% and its Debt-to-Equity ratio is 1.8, we substitute the values into the formula as follows:
ROE = 0.068 × (1 + 1.8)
ROE = 0.068 × 2.8
ROE = 0.1904
After rounding to three decimal places, Company B's ROE is 0.190.
