Answer:
249
Step-by-step explanation:
let n(U) be the total number of school
employees =800
Let n(1) be amount of instructors = 430
Let (F) be full-time faculty = 589
Let n(InF) be the instructors who were full-time
faculty = 340
The number of employees who were full-time
faculty but were not instructors is expressed as:
n(FnI") = n(F) - n(InF)
n(FnI') = 589 - 340
n(FnI'") = 249
Hence the number of school employees who
were full-time faculty but were not instructors
are 249
