Please use excel format and use excel solver for linear programming.

For the project with below information, we would like to crash the project duration to 49 days. Please using linear programming (LP) to find the optimal solution for us to crash individual activities to minimize the crashing cost. Please complete the LP formulation first in the Excel file. After the LP formulation, please set up the Excel and Excel Solver, and then run the Excel Solver for an optimal solution. What is the minimized crashing cost? How do you interpret the optimal solution? What will be the project total cost after the crashing based on the optimal solution? Please address the questions in Excel file. Please provide your detailed work in the Excel file, which should allow me to track the processes and rerun Excel Solver for solutions. To help you verify your work, the minimized cost from project crashing is $3450. Objective coefficients Decision Variables Minimize cost S.T.
