The easy way to do this is to remember the gas laws. Pressure increases with increasing temperature. Therefore, if T is going from 82C to -28C you know it is being cooled which means the pressure will decrease. So make the factor so you get a smaller number. Remember T must be in kelvin.
Final P = 1.20 atm x (T factor)
Final P = 1.20 atm x (T factor)
