Optimization Techn Industr Eng examJust please give me good answer for the file I attach. And you need to use excel to solve the last answer.

Final Exam

Instead of floating point arithmetic, it is recommended to do arithmetic with fractions. Solve the problems using the methods you learned in class (Optional ways you google will not earn any point).
