He closed the PDF and opened his final report. The numbers looked perfect. The Net Present Value of Plant B was $2.3 million higher. The IRR exceeded the MARR by 4%. He submitted the file at 6:14 AM, just as the first gray light of dawn bled through the library windows.

The PDF was ruthlessly efficient. Chapter 1: Time Value of Money. One page. “Money today is worth more than money tomorrow. Full stop.
