However he has been working slower than normal, producing an average of 15 puzzles for every 4 days. How fast will Quentin have to work now to get the book finished on time?
AnswerQuentin will never get the book in on time. He is on his 80th day. If he has been producing 15 puzzles for 4 days then, 15*(80/4)=300.
