Lizzy: A TV show has been going on for 14 years. Out of those 14 years, 8 seasons had 15 episodes, 4 seasons had 20 episodes, and 2 seasons had 12 episodes. What is the average number of episodes per year?.
Me: Hmmm, let me think. I think this is the detailed solution:
8 seasons with 15 episodes had 8 x 15 = 120 episodes. 4 seasons with 20 episodes had 4 x 20 = 80 episodes. 2 seasons with 12 episodes had 2 x 12 = 24 episodes. All together, there have been 120 + 80 + 24 = 224 episodes. The average number of episodes a year is 224 / 14 = 16 episodes. Final answer: 16.
