A formula involving atmospheric pressure and height above sea level is shown by d=500log(p-2) / 27, where d is the distance above sea level, in kilometres, and p is the atmospheric pressure, in kilopascals (kPa). If a balloon floats to a height of 10km above sea level, what is the atmospheric pressure, to the nearest hundredth of a kilopascal, at that height?
