Answer:

Let's find out!

Today's my B'day!

So, to calculate this, we need a equation.

(Let x= # of people in 1980)


100,000+2,000-3,000+10,000=x\\109,000=x

See? Easy... wait? It's not the solution?

Oh! Made a Mistake!

Why you always check!


100,000+2,000-3,000+10,000-1,000=x\\108,000=x

There you go!

Even Experts can make mistakes!

Hope this helps!

P.S. Stay Safe!
