A firm is considering two mutually exclusive projects, X and Y$,$ with the following cash flows:

$01234$

Project X $-$$$1,000$ $$90$ $$280$ $$430$ $$700$

Project Y $-$$$1,000$ $$1,100$ $$90$ $$50$ $$50$

The projects are equally risky, and their WACC is $10\%.$ What is the MIRR of the project that maximizes shareholder value? Do not round intermediate calculations. Round your answer to two decimal places.
