Okay kiddo, let's talk about the 20 grand. Simply put, 20 grand is just a way of saying 20,000 dollars.
Now, you may be wondering why we use the word "grand" instead of just saying 20,000 dollars. Well, it's just a slang word that some people use instead of saying the full amount.
Think of it like a nickname for money. Just like how your friends might call you by a nickname instead of your full name, some people use nicknames for money too.
So, when you hear someone say "I made 20 grand last year", they are just saying that they made 20,000 dollars. It's really that simple!
