$($MIRR calculation$)$ Artie's Wrestling Stuff is considering building a new plant. This plant would require an initial cash outlay of $$7$ million and would generate annual free cash inflows of $$3$ million per year for $7$ years. Calculate the project's MIRR given:

a$.$ A required rate of return of $10$ percent

b$.$ A required rate of return of $11$ percent

c$.$ A required rate of return of $16$ percent

a$.$ If the required rate of return is $10$ percent, what is the project's MIRR?

$\%($Round to two decimal places.$)$

b$.$ If the required rate of return is $11$ percent, what is the project's MIRR?

$\%($Round to two decimal places.$)$

c$.$ If the required rate of return is $16$ percent, what is the project's MIRR?

$\%($Round to two decimal places$)$
