The wage per day of 40 men is $500 each and the other 40 men is $300, each for 8 hours work per day. The fine for the delay in the work is $10,000 per day. 1st question: How many more men should the contractor add in order to complete the work on time? 2nd question: Assuming that the additional men to be added will be paid $400 per day, will the contractor save money by employing enough men to complete the work on time or by not adding more men and just pay the fine?
