a$.)$ For which of these projects is the IRR rule reliable?

The IRR rule for $\_\_\_\_\_.$ Unless all of the $\_\_\_\_\_$ cash flows of the project precede the $\_\_\_\_\_$ ones, the IRR rule may give the wrong answer and should not be used. Furthermore, there may be multiple IRRs or the IRR may not exist.

b$.)$ Estimate the IRR for each project $($to the nearest $1\%).($round final answers to the nearest $1\%).$

The IRR for project $1$ is $\_\_\_\_\_\%$

The IRR for project $2$ is $\_\_\_\_\_\%$

The IRR for project $3$ is $\_\_\_\_\_\%$

c$.)$ What is the NPV for each project if the cost of capital is $5\%?20\%?50\%?($round final answers to the nearest cent$)$

NPV for project $1,$ cost of capital $5\%,20\%,$ and $50\%$

NPV for project $2,$ cost of capital $5\%,20\%,$ and $50\%$

NPV for project $3,$ cost of capital $5\%,20\%,$ and $50\%$
