Aproduction facility produces metal fasteners, and realizes a profit of $800 per machine per month for 10 machines. each machine requires cooling water to keep it running effectively. management wishes to install more machinery, but the cooling water available cannot keep up with unlimited demand, and adding more machines would cause them all to run more slowly. each additional machine reduces profit by $25 per month. thus with 10 machines, the profit is $8000 (= 800 x 10). for 11 machines the profit is $8525 [= (800 – 25) x 11]. likewise for 12 machines, the profit is $9000 [= (800 – 2(25)) x 12]. determine the optimum number of machines that should be installed to maximize profit.

Employees at a library check out books to patrons. books have an isbn and a name. the library sometimes has multiple copies of the same book. books have one or more authors. a patron is an individual who has an active (non-expired) library card. for each library card, we store the person's first and last names and their address. for each employee, we store their employee id, current salary, first and last name and their address. we also store the employee id of their current manager. each time we check out a book to a patron we need to store the date of the transaction, the employee who checked out the book to the patron, and the library card of the patron. some employees have library cards. if an employee patron turns in a book late, the fine that they pay is a percentage of their salary. some employees are authors who have library cards—they are allowed to check out as many books as they like.
