◼ 5) Break-even analysis. A publisher for a promising new novel figures fixed costs (overhead, advances, promotion, copy editing, typesetting) at $55,000, and variable costs (printing, paper, binding, and shipping) at $1. for each book produced. If the book is sold to distributors for $11 each, how many must be produced and sold for the publisher to break even? ◼ 6) Suppose that the number of hours a store is open to the number of daily customers is constant. When the store open 8 hours, the number of customers is 92 less than the maximum number. When it opens 10 hours the number is 46 less than the maximum number. Find the maximum number of customers.
