Final answer:
DTO, Incorporated's net income is $4 million, calculated by multiplying its sales of $40 million by the profit margin of 10%. The Return on Assets (ROA) is 19.05%, found by dividing the net income by the total assets of $21 million.
Step-by-step explanation:
DTO, Incorporated has reported sales of $40 million. With a profit margin of 10%, the net income can be calculated by multiplying the sales by the profit margin: $40,000,000 * 10% = $4,000,000. Therefore, the net income is $4 million.
Next, to calculate the Return on Assets (ROA), we divide the net income by the total assets. The ROA is calculated as follows: $4,000,000 / $21,000,000 = 0.190476, or approximately 19.05%. Therefore, the ROA for DTO, Incorporated is 19.05%.
In comparison, the self-check question from the reference material can help reinforce the concept of calculating accounting profit. The firm's accounting profit is calculated by subtracting the explicit costs from the total revenues: $1,000,000 - ($600,000 + $150,000 + $200,000) = $50,000. Not directly related to DTO's situation, but it provides a basic example of profit calculation.
