I received a letter from Pepco (Potomac Electric Power Co.) that informs me of a rate increase from $0.0649 per KWh to $0.1008 per KWh.
Several times in the letter, they describe this increase as being a 38% increase. It's not a typo, because it's repeated several times... but I don't understand how they arrived at 38%.
If you multiply $0.0649 by 1.38, the total is $0.0895.
I'm no whiz with a calculator, but the increase appears to be about 55% more than the original rate.
Am I doing something wrong? Is my math incorrect, or is Pepco pulling a fast one? What math games and trickery are they using? Help me to understand.
