#P_"Total"=(20+42.8)*atm=62.8*atm#

Explanation:

Datlon's law of Partial Pressures states that in a gaseous mixture, the partial pressure exerted by a gaseous component is the same as the pressure it would exert if it ALONE occupied the container. The total pressure is the SUM of the partial pressures.

For your problem #P_"Total"=P_"dinitrogen"+P_"dioxygen"# #=# #(20+42.8)*atm#.
