Hey, I'm a student in finance and I don't understand well this question, could you please explain to me how to respond and the formula to use? Thanks in advance

"You're a successful entrepreneur. You are currently studying the opportunity to implement a new production site. The complete installation of the plant should cost you 105.9 million euros, to be paid immediately if the decision to invest is taken. You expect the plant to generate a profit of 9.6 million euros in one year. To put it simply, you ignore any possibility of liquidation of the project, so the profits are assumed to be perpetual. On the other hand, in order to take into account the impact of competition, you think that profits will decrease at a rate of 2.72% per year.

Be sure to determine the internal rate of return.

You will indicate 4 decimal places after the decimal point in your answer."
