Concept explainers
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.

The data in the Excel Online file below show the total expenses ($), the percentage of the total budget spent on administrative expenses, the percentage spent on fundraising, and the percentage spent on program expenses for 10 supersized charities. Administrative expenses include overhead, administrative staff and associated costs, and organizational meetings. Fundraising expenses are what a charity spends to raise money, and program expenses are what the charity spends on the programs and services it exists to deliver. The sum of the three percentages does not add to 100% because of rounding. Construct a spreadsheet to answer the following questions.
