Percent markup |

From Dan:
If a product cost $2.00 and sells for $2.00 there is 0% markup
If a product cost $2.00 and sells for $4.00 there is a 100% markup
If a product costs $2.00 and sells for $6.00 there is a 200% mark up ------which I don't understand I would think that the markup would be 300%
If a product costs $2.00 and sells for $8.00 there is a 300% mark up---- " " " " " " " " " " 400%

The trinity concept says three is one. |
2005-09-17 |
|
From Kevin:
The trinity concept says three is one. Mathematically, I will attempt to proof this.
Let G be God and T trinity. We start with
G = T
2G = 2T Double both sides
G + 2G = G + 2T Add G on both sides
3G = G + 2T Simplify
3G - 3T = G + 2T - 3T Subtract 3T on both sides
3(G - T) = G - T Factor 3 on the left, simplify on the right
3 = 1 Divide (G - T) on both sides.
But how can three equals one? Can it?
