I believe you have to write this yourself, so I'll give you a basic idea of what to write, and everything that's in capital letters you have to decide what it's supposed to be.
A PERSON has x of SOMETHING, and they GIVE/TRADE/SELL/LOSE 100 of it. Now they have 40 of it.
Hopefully this helps! If you have any more questions or don't understand, please comment or DM me, and I'll get back to you ASAP. :)
