Ms. Valdoz offered you a job which should be completed within 50 days. At present, you have xxx workers. (xxx would be the last 3 digits of your student number.) In estimate, you can finish the job in 80 days. In the xxx men, the first 10 are paid at P190/day, next 10 at P220/day, and the rest at P300/day. For each day beyond the original 50 days, you have to pay P2,000 liquidated damages. How many more men should you hire to complete the job on time? If the first 5 men you hire are paid at P220/day and the rest at P190/day, would you save more money by hiring additional men or by just paying the fine?
