Answer:
The number is 
Step-by-step explanation:
From the question we are told that
The sample size is n = 800
The number of seniors is S = 519
The number of commuters is C = 430
The number of of seniors that are commuters is 
Generally the number of 800 surveyed students who were seniors or were commuters is mathematically evaluated as
=> 
=>
