Question 26194
Let number of 2-person stations be "x".
Then number of 3-person stations is "16-x"
Persons accommodated at the 2-person stations is 2x.
Persons accommodated at the 3-person stations is 3(16-x)=48-3x
EQUATION:
#of persons at 2-person + #of persons at 3-persons = 38
        2x + 48-3x=38
               -x=-10
                x=10 (# of 2-person work stations)
