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?

How many solar systems are there? ** If there are 8 more solar systems for every planet in the galaxy, there are 8+1 = <<8+1=9>>9 solar systems for every planet.
How many solar systems are there? ** Since the number of planets is 20, there are 20*9 = <<20*9=180>>180 solar systems in the galaxy.
How many solar systems and planets are there altogether? ** Altogether, there are 180+20 = <<180+20=200>>200 solar systems and planets in the galaxy.
