The NVP equation (Equation 6.23) is described as follows:
NVP = -P+ m=1nC(m)(1+i)m+ CR(1+i)n, m=1 to n (6.23)
The NVP equation is important for evaluating project-based investments. It is also a basic equation for defining the concept of "value addition", and has broad philosophical implications for what engineers do. Explain.
