Inventories OHaganBooks.com currently operates three warehouses: one in Washington, one in California, and the new one in Texas. Exercises 25–30 are based on the following table, which shows the book inventories at each warehouse:
Sci Fi | Horror | Romance | Other | Total | |
Washington | 10,000 | 12,000 | 12,000 | 30,000 | 64,000 |
California | 8,000 | 12,000 | 6,000 | 16,000 | 42,000 |
Texas | 15,000 | 15,000 | 20,000 | 44,000 | 94,000 |
Total | 33,000 | 39,000 | 38,000 | 90,000 | 200,000 |
Take the first letter of each category to represent the corresponding set of books; for instance, S is the set of sci fi books in stock, W is the set of books in the Washington warehouse, and so on. In each exercise, describe the given set in words, and compute its cardinality.
