<human>:  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?
<bot>: 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.
