Which three tools of the trade do you think are most important and why?

Well first off , researchers show that 1.) location and 2.) product are very important details when it comes to trade. 3.) Would be profit.

Take Ghana for example : 1.) Ghana sat right in the middle of the trade route, this helped greatly because everyone would run through/into it.

2.) Product : Ghana was trading salt,gold, and sometimes silver. These were very rare and popular and expensive back in that time frame, so everyone wanted some of the three.

3.) Your profit takes a toll on people so you  would need a reasonable price and attitude when trading. This is how con artists "finesse" many people.

I really hope that this helps you out a lot! & Have a very wonderful day :)
