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.

- Large companies typically collect volumes of data before designing a product, not only to gain information as to whether the product should be released, but also to pinpoint which markets would be the best targets for the product. Several months ago, I was interviewed by such a company while shopping at a mall. I was asked about my exercise habits and whether or not I'd be interested in buying a video/DVD designed to teach stretching exercises. I fall into the male, 18 – 35-years-old category, and I guessed that, like me, many males in that category would not be interested in a stretching video. My friend Amanda falls in the female, older-than-35 category, and I was thinking that she might like the stretching video. After being interviewed, I looked at the interviewer's results. Of the 97 people in my market category who had been interviewed, 16 said they would buy the product, and of the 101 people in Amanda's market category, 31 said they would buy it.

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.
