To calculate the Return on Equity (ROE), we need to use the formula:

$\text{ROE} = \frac{\text{Net Income}}{\text{Equity}} \times 100$

First, we need to determine the equity of the firm, which can be calculated as follows:

$\text{Equity} = \text{Total Assets} - \text{Total Liabilities}$

Step 1: Calculate the firm's equity

$\text{Equity} = 8,000 - 3,600 = 4,400$

Step 2: Calculate Return on Equity (ROE)

$\text{ROE} = \frac{650}{4,400} \times 100 = 14.77\%$

Therefore, the firm's Return on Equity (ROE) during the year is 14.77%.
