The document contains several tables showing profit and loss statements, costs, sales, and key metrics for different industries. The first table shows that with $100 in November sales, $50 in costs of sale, and $40 in fixed costs, the original profit was $10. When sales dropped to $90, profit became $0. The second table shows the effects of a 10% increase in fixed costs on the original profit. Subsequent tables show days sales outstanding and profit margins by industry.
