Show me the steps to solve Suppose you invest $$$$4$ comma $000$ today and receive $$$$11$ comma $000$ in $5$ years.

a$.$ What is the internal rate of return$($IRR$)$ of this$$ opportunity?

b$.$ Suppose another investment opportunity also requires $$$$4$ comma $000$upfront$,$ but pays an equal amount at the end of each year for the next $5$ years. If this investment has the same IRR as the first$$ one, what is the amount you will receive each$$ year?
