I did my math wrong in my last post.
This was my equation:
z + m(y – 400) = x
But the 400, the amount I spend on gas a month was wrong. I checked it the other day after I filled up my car, a 2007 Kia Rio (see photo), and I got 37 mpg. I average only $265/month for gas. The new equation should read:
z + m(y – 265) = x
So I should really plug in the new numbers and update my math an all but I know it won’t make a huge difference so I’m just going to show you the promised picture of my Kia Rio.
