Consider a homebuyer/investor who plans to buy a new house, the price of which is $ 500,000. Suppose the buyer does not have any initial savings for the down payment. To buy the house, he needs to borrow $ 500,000 from a bank in the form of a mortgage loan. The mortgage is a 15-year-fixed-rate mortgage. If interest rate is 10 percent, compute the annual payment of the homebuyer.

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.
