Hi careercapital25.
Those concepts are not directly discussed in the
TTP course, but they do appear in a number of practice questions in the course. So, by doing the practice questions you can get a fair amount of exposure to them.
Meanwhile, you can learn about the interactions between supply and demand and prices by doing a quick internet search on those topics. though they are pretty intuitive.
When the supply of something increases, all else equal, the price decreases.
When supplies of something become tighter, the price increases.
When, the price of something decreases, demand for that thing increases.
When good news about something comes out, demand for that thing increases.
You get the idea. What you'd expect to happen is generally what occurs.
Regarding revenue, here are the key concepts to understand.
profit = revenue - costs
revenue = total number of products or services sold x price
profit margin = profit/revenue (in percent, ex. $40 profit/$100 revenue means a 40% profit margin.)
