we know that the mean of the salaries of 2 people = 4382
one person earns 3388 per month
so the arithmetic mean, the average is 4382
lets say x= salary person 1 3388 is salary of person 2
(x+3388)=4382*2
x=(8764-3388)
x=5376
the salary of person 1 is 5376 dollars per month
we check:
if we add 5376+3388=8764
8764/2=4382
