Raphael has a coupon to Bookstore A for $12.00 off the list price of a book. Bookstore B sells the same book for 20% less than the list price. After doing some calculations, Raphael discovers that, with the discounts, the book costs twice as much at Bookstore B as it costs at Bookstore A. What is the list price of the book? Solve the equation. Say aloud what you do at each step.
