If the appropriate discount rate on these projects is 10 percent, which would be chosen and why?

If the appropriate discount rate on these projects is 10%, then the project with a higher net present value (NPV) should be chosen. The NPV is determined by subtracting the initial cost of a project from its expected future cash flows and then discounting those cash flows back to their current value based on the chosen discount rate. Therefore, if one project has a larger NPV than another then it indicates that it will generate more profit for the company given its cost and expected returns over time.

In this case, choosing the project with higher NPV would provide greater return on investment in a shorter period of time which makes it more desirable than other options. Additionally, selecting a lower risk option with guaranteed returns is generally preferred as opposed to risking capital on speculative ventures. Ultimately, using the NPV calculation when assessing potential investments can help organizations make decisions regarding which projects are most suitable for their needs while also providing maximum return on investment.
