To calculate the total pressure of the system, we use Dalton's Law of partial pressure where it says that the total pressure of the gases in a system is the sum of the partial pressures of each component in the mixture. Therefore,

P = 100 kPa + 24 kPa + 30 kPa + 26 kPa = 180 kPa

the total pressure in the system is 180 kPa.
