$($MIRR$)$ Star Industries owns and operates landfills for several municipalities throughout the Midwestern part of the U$.$S$.$ Star typically contracts with the municipality to provide landfill services for a period of $20$ years. The firm then constructs a lined landfill $($required by federal law$)$ that has capacity for five years. The $$10\mathrm{.}2$ million expenditure required to construct the new landfill results in negative cash flows at the end of years $5,10,$ and $15.$ This change in sign on the stream of cash flows over the $20-$year contract period introduces the potential for multiple IRRs, so Star's management has decided to use the MIRR to evaluate new landfill investment contracts. The annual cash inflows to Star begin in year $1$ and extend through year $20$ are estimated to equal $$3\mathrm{.}3$ million $($this does not reflect the cost of constructing the landfills every five years$).$ Star uses a $10\mathrm{.}2\%$ discount rate to evaluate its new projects, so it plans to discount all the construction costs every five years back to year $0$ using this rate before calculating the MIRR.

a$.$ What are the project's NPV$,$ IRR, and MIRR?

b$.$ Is this a good investment opportunity for Star Industries? Why or why not?

a$.$ The project's NPV where the discount rate is $10\mathrm{.}2\%$ is $ million. $($Round to two decimal places.$)$

The project's IRR is $\%.($Round to two decimal places.$)$

The MIRR of the project with a discount rate of $10\mathrm{.}2\%$ is $\%.($Round to two decimal places.$)$
