The quiz has 10 questions. You will need LPsolve to solve questions 7 to 10.
Tip: work on questions 7 to 10 separately.
(i.e., cut and paste each formulation to LPsolve, solve it, save the problem and close LPsolve
... then, open LPsolve again and repeat the process for the next question)
You have four hours to finish the quiz.
