Final answer:
To determine the first priority project for SIMSOX, compare the rate of return for each project. If any other projects also meet or exceed SIMSOX's expectation, they can be funded in order of priority based on ROI.
Step-by-step explanation:
In order to determine the first priority project for SIMSOX, we need to compare the rate of return for each project. The project with the highest rate of return should be the first priority. If any other projects also have a rate of return that meets or exceeds SIMSOX's expectation of 20 percent, they can be funded as well, but in order of priority based on return on investment.
Unfortunately, the specific projects and their rates of return are not provided in the question. If you provide that information, I would be happy to help you determine SIMSOX's first priority project and the order of priority for the other projects.
