2. Jimmy was drawing rectangles at his desk. After a while he concluded that if you increased one of the sides by 10% and decrease the other side by 10% the area won't change. Is Jimmy correct? Provide a formal mathematical argument as well as a "teacher response" to Jimmy.
A contractor has a contract which which will expire in 40 days. At present, he has 80 men on the job and can finish the job in 50 days. 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? If any, how much is the savings? No overtime work is permitted.

The officers of a high school senior class are planning to rent buses and vans for a class trip. Each bus can transport 72 students, requires 5 chaperones, and costs $1,400 to rent. Each van can transport 8 students, requires 1 chaperone, and costs $120 to rent. Since there are 432 students in the senior class that may be eligible to go on the trip, the officers must plan to accommodate at least 432 students. Since only 50 parents have volunteered to serve as chaperones, the officers must plan to use at most 50 chaperones. How many vehicles of each type should the officers rent in order to minimize the transportation costs? What are the minimal transportation costs? The officers should rent buses and The minimal transportation costs are $ vans to minimize the transportation costs.
