chemistry please help i cant figure this out

What is the total mmHg pressure in of a gas mixture containing argon gas at 0.25atm , helium gas at 385mmHg , and nitrogen gas at 345torr. ? sorry i didn't relize i left them out.
0.25 atm x (760mm/1 atm) = ? mm Hg Ar.
385 mm Hg He = 385 mm Hg He.
345 torr N2 = 345 mm Hg N2.
Ptotal in mm Hg = pAr + pHe + pN2 = ?
