Paying taxes at SLC?

I am planning to park my car at Salt Lake City airport for the whole week when I travel in a couple of weeks time. I know this is possible. I also know it is expensive. Only I am not sure exactly how expensive, as I assume tax has to be added onto the fees. How much is this?

Hi. As far as I cant make out your taxes will come to five per cent. It seems however that you have to pay by the hour. Are you sure you want to do this? It seems a lot of money to pay I am sure you can park your car elsewhere securely. I wouldnt do it for sure
