A farmer bought a horse for $50.00
Then he sold it for $60.00
He had second thoughts about the horse, and he bought back the horse for $70.00
And then he sold it again for $80.00
What is the financial outcome of these transactions

Add all the money the farmer paid for the horse. Add all the money the farmer got from selling the horse. Did he spend more than he got?

My answer was $20. He paid $120, he spent $140. Yes,but I subtracted 120 from 140 and got 20.

I believe you have it. You said he paid $120. That is correct. You said he spent $140. I think you meant to say he received $140.
