Then, for example, the cost of reducing the duration of activity H from 12 days to 9 days is c(3)  300(3)2  $2700. Modify the Project Crashing Linear.xlsx model to accommodate this quadratic function, and then optimize to meet a deadline of 54 days. (You can still assume that activity H can be crashed by a maximum of 4 days.) Now you must use GRG Nonlinear Solver.
