At a Halloween party, you play a dart game where you win teeth based on where your dart throw lands. The probability of hitting the outer ring is 8% and you win 5 teeth. The probability of hitting the yellow ring is 26% and you win 6 teeth. The probability of hitting the blue ring is 34% and you win 7 teeth. The probability of hitting the orange ring is 20% and you win 9 teeth. The probability of hitting the bullseye is 12% and you win 12 teeth. If you have to pay 8 teeth to throw a dart, what is your mathematical expectation for playing this game? Answer should be in terms of teeth rounded to the hundredths place.
