Final answer:
The residual income of the new project is calculated by subtracting the required rate of return multiplied by the investment from the net operating income. The calculation leads to a residual income of $300 for the new project.
Step-by-step explanation:
The student is asking about calculating the residual income of a new project. To find the residual income, we subtract the product of the required rate of return (which is 18% for this company) and the investment amount from the project's net operating income. In this case, it's $3,000 net operating income minus the product of 18% and $15,000 investment:
$3,000 - (0.18 Ă— $15,000) = $3,000 - $2,700 = $300.
Therefore, the residual income of the new project is $300, which corresponds to option D.
