On bitterly cоld dаys, cаrs will оften give а "pressure warning" fоr the tires. During the summer when the temperature is [x] degrees Celsius, a car's tires have a pressure of [y] atm. However, on the coldest day of the year, the temperature fell to -[z] degrees Celsius. What would you expect the tire pressure to be on the coldest day (in atm)? Assume the volume and amount of gas in the tire remains constant. Round your answer to the nearest tenth place.
