Use a variation model to solve for the unknown value. A chef self-publishes a cookbook and finds that the number of books she can sell per month varies inversely as the price of the book. The chef can sell 1600 books per month when the price is set at \( \$ 9 \) per book. Part: \( 0 / 4 \) Part 1 of 4 (a) How many books would she expect to sell per month if the price were \( \$ 12 ? \) If the price is \( \$ 12 \) per book, books are sold.
