Fuzzy Math
This afternoon we went over to Rader Mazda to have the car’s 7500 mile service done. When I called and made the appointment the other day I asked how much it was going to be. It is a glorified oil change, but they inspect a bunch of stuff and rotate the tires. I was told it would be $74 and change. About what I figured. I saved a coupon the dealer had sent me earlier, so I’d get 10% off that to boot. When the car was finished and it was time to settle the bill they told me it was $72.13. About right I thought, 74 + tax – 10% = $72 and change.
When we got home I looked at the invoice. Huh? Mazda “B” service, Labor $108 (1-1/2 hours), parts $21.09 (oil, filter, gasket and something called SOLVENT,WIND) and tax $1.48 for a grand total of $130.57. How come I paid only $72.13 and how did they arrive at that figure?
