Simple % problem

This will seem super easy to people with good maths brains but I am failing to make sense of it.

I am simply trying to figure out sales profit shown as percentage.
An example from the image attached:
Manganese Alloy costs $35200 to produce and sells for $269100, resulting in a profit of $233900
I have tried 2 formulas to try determine what percent the profit is:
|| 233900 / 269100 x 100 = 86.9 but does 86.9 represent the profit?
|| 269100 / 35200 x 100 = 764.5

My great confusion comes in when I try, as a hypothetical test, to sell for the same cost as production ($35200 sold for $35200). This is obviously a profit of zero but comes out as 100%, I know 35200 is 100% of 35200 but Im trying to derive the sales profit and not the value of one figure against another.
As you can see Im getting myself twisted in a knot.

Thank you for your help.

 

the formula to find the profit percentage is:

Profit Percentage = Net Profit / Cost
Net profit = Total Revenue - Total Expenses
Revenue = Selling Price


Manganese Alloy costs $35200 to produce and sells for $269100, resulting in a profit of $233900
Cost=$35200
Total Revenue=$269100
Net profit =$269100-$35200=$233900

Net Profit Margin =233900 / 269100 x 100 = 86.9%
Profit Percentage =(233900/35200)=664.49%

Answer:
Net Profit Margin: 86.92%
Net Profit: $233,900.00
Profit Percentage: 664.49%

 

Wow! What math course is this? Is this really considered advanced mathematics? I had no idea that you also know business math.

 

financial math, might be accounting or economics

 

This is not your specialty. Nonetheless, you were able to find a solution. This is fascinating to me. You dit not major in finance math or economics..

 

My apologies guys, it should have been under Basic Math, I don't know how I over looked that.
Thank you for your help, I really appreciate it.

 

No problem.

 

no need for apology
actually Revenue, Cost, and Profit Functions are part of
Finite Math
