Answer:
The initial investment is $2,915,000. The annual net operating income is $485,000. The project's simple rate of return is the annual net operating income divided by the initial investment.
The variable expense ratio is 45%, which means that the variable expenses are $2,863,000 x 45% = $1,288,350.
The contribution margin is $2,863,000 - $1,288,350 = $1,574,650.
The fixed expenses are $781,000 + $583,000 = $1,364,000.
The net operating income is $1,574,650 - $1,364,000 = $210,650.
The simple rate of return is $210,650 / $2,915,000 = 7.22%.
Therefore, the project's actual simple rate of return is 7.22%.
