I have a question regarding this problem. Can someone help me understand how to get the economic value of free cash flows (FCF's)?:

Data:

The Growth period is 5 years (growth rate=100%; r=10% and ROIC=20%). The Early Maturity period is 15 years (growth rate=10%; r=12% and ROIC=50%). The Late Maturity Period is forever. (growth rate=3%; r=8% and ROIC=8%). Also, The amount of invested capital at the very start is $3m

Question:

What is the economic value at t= 0 of the FCF's MACKing will generate during the early maturity period and during the late-maturity period?
