GDT has never looked at a Harry Potter book, but according to the Wikipedia "the Harry Potter books are a series of fantasy novels by British writer J. K. Rowling.""Amazon.com announced that first-day pre-orders for 'Harry Potter and the Deathly Hallows' were 547 percent higher than first-day pre-orders for 'Harry Potter and the Half-Blood Prince' the sixth book in the series." "Amazon.com is currently selling 'Harry Potter and the Deathly Hallows' for just $18.89 (hardcover), a savings of 46 percent."
Assume zero knowledge of percents and percentages. Observe the following.
100%represents the "whole" of something. For example, if Zelmo ate
100%of the pie, then he ate the whole pie. Percentages larger than
100%arise when percentage differences between two numbers is used instead of amount differences.5 increased 100% is 10 5 increased 200% is 15 5 increased 300% is 20 5 increased 400% is 25 5 increased 500% is 30 5 increased 600% is 35
