Lizzy: Today, at the school science lesson, Jake learned that there are 8 more solar systems for every planet in the galaxy. If there are 20 planets in the galaxy, how many solar systems and planets are there altogether?.
Me: Hmmm, let me think. I think this is the detailed solution:
If there are 8 more solar systems for every planet in the galaxy, there are 8 + 1 = 9 solar systems for every planet. Since the number of planets is 20, there are 20 * 9 = 180 solar systems in the galaxy. Altogether, there are 180 + 20 = 200 solar systems and planets in the galaxy. Final answer: 200.
