You can  put this solution on YOUR website! You sell widgets. Your equipment costs you a total of $1000. Each widget costs $100 to make, and you sell it for $200. 
What is your revenue for selling X widgets?:: 200X dollars 
----------------------------------------------- 
What is your cost for making X widgets?:: 1000+100X dollars 
---------------------------------------------------- 
What is your profit for selling X widgets?:: 
Revenue - Cost = 200X - [1000+100X] = 100X-1000 dollars

You can  put this solution on YOUR website! Your fixed cost is $1000.  Whether you make 1 or 1,000,000 widgets, this doesn't change.  $100 * x is your variable cost.  It changes based upon how many widgets you make. 
. 
The formula, therefore, is: 
Cost of making x widgets = 1000 (fixed) + x*100 
Cost = 1000 + 100x 
. 
The revenue is the gross amount you take in.  Since each of them costs $200, it would be: 
Revenue = 200x 
. 
Your profit seems like a lot (100 on each item).  That's the case if you sell a lot.  But if you only sell a few, you'll be in the red due to your fixed cost. 
Profit = Revenue - Cost  
P = 200x - (1000+100x) 
. 
Let's see how this works in the real world.   
If you see 10 widgets, your revenue is 10*200=2000 
Your cost would be 1000(fixed) + 10*100(variable) or 2000 
Profit = 0 
This is your break-even point. 
. 
However, if you have a great marketing department and a great product, let's say you sell 90. 
Revenue = 90*200 = 18000 
Cost would be 1000(fixed) + 90*100(variable), or 11000 
Profit = 7000
