Draw an ERD for each of the following situation. (If you believe that you need to make additional assumptions, clearly state them for each situation).

Each publisher has a unique name; a mailing address and telephone number are also kept on each publisher.
A publisher publishes one or more books; a book is published by exactly one publisher.
A book is identified by its ISBN, and other attributes are title, price, and number of pages.
Each book is written by one or more authors; an author writes one or more books, potentially for different publishers.
Each author is uniquely described by an author ID, and we know each author's name and address.
Each author is paid a certain royalty rate on each book he or she authors, which potentially varies for each book and for each author.
An author receives a separate royalty check for each book he or she writes.
Each check is identified by its check number, and we also keep track of the date and amount of each check.
As you develop the ERD for this problem, follow good data naming guidelines.

You are evaluating two different silicon wafer milling machines. the techron i costs $285,000, has a three-year life, and has pretax operating costs of $78,000 per year. the techron ii costs $495,000, has a five-year life, and has pretax operating costs of $45,000 per year. for both milling machines, use straight-line depreciation to zero over the project’s life and assume a salvage value of $55,000. if your tax rate is 24 percent and your discount rate is 11 percent, compute the eac for both machines.
