I'll give you a question, please answer with step-by-step reasoning process.
Joe found a new series to watch with a final season that will premiere in 10 days. The series has 4 full seasons already aired; each season has 15 episodes. To catch up with the season premiere he has to watch all episodes. How many episodes per day does Joe have to watch?

6
The total number of episodes is 4 seasons x 15 episodes / season = 60 episodes.

Joe has to watch per day 60 episodes ÷ 10 days = 6 episodes / day.

Final answer: 6
