Want to know about commerce section

I built commerce in Facility section but now i don't know what is the "MARKUP"stands for???? what happen if i increase "MARKUP" & "MARKETERS" boath????   plzzz help me.....

Markup is the amount of profit u want to make from this product. Its for 1 item. The amount of marketers will help sell more. Therefore, if u have lots of marketers, your products will be known more and u will sell more. But honestly, I dont recommend investing too much on commerce. But its a good way if u are in the red a bit.

It is one of the ways to make money if you never or very rarely earn prize money.  I have found it very useful if you are in the red too.

What is the best number to put the markup at? If anyone knows.

I found 50 to be better than 60

I run it at 55% highest quality with all staff on clothing, 83 staff gives me 1.5m per race.

i believe the magic number is 44
I B if you run at 44 markup on clothing your profit from clothing will be 1607760 as long as you keep 83 marketers assigned
