Answer:
The answer is B ...........
Answer:
5.85 years
Step-by-step explanation:
Overall number of associates employed = 117
Number of associates employed per year = 20
Average = Total number of associates employed ÷ number of associates employed per year = 117 associates ÷ 20 associates per year = 5.85 years
, and 
. This gives a remainder of
, and 
. This gives a new remainder of
, and 
. This gives a new remainder of
and so there is no remainder.
###
Quicker method: Use the polynomial remainder theorem, which says the remainder upon dividing a polynomial 
by 
is 
. Here we have
(-6m^7 + 20m^6) = 2m^4(-3m^3 + 10m^2)
Therefore, (-6m^7 + 20m^6) ÷ 2m^4 = -3m^3 + 10m^2
