Magic Realm, Inc., has developed a new fantasy board game. The company sold 15,000 games last year at a selling price of $20 per game. Fixed expenses associated with the game total $182,000 per year, and variable expenses are $6 per game. Production of the game is entrusted to a printing contractor. Variable expenses consist mostly of payments to this contractor. Management is confident that the company can sell 18,000 games next year (an increase of 3,000 games, or 20%, over last year). Given this assumption: What is the expected percentage increase in net operating income for next year?
