In the problem statement, the phrase "...based on number
of sales per number of employees..." tells us how to set
up the fractions for calculating the individual employee
percentages. Then calculate total team percentages based
on those percentages and the number of employees on each
team.
So, "team number of sales" is the numerator, "number of
employees" is the denominator, and "per" means divide.
64+60=124........"total #units" sold collectively by both teams
Team1:
(#units) / (#employees)=64/12=5.33units per employee
(%sales) / employee=(units per employee)/(total units)
=(5.33/124)x100
=(4.30%) / employee
Team1 sales percentage=(4.30%)x12 employees
=51.61% of total sales
Note: This percentages could have been found by simply
dividing (Team1 total #units) / (total #units)
Team2:
(#units) / (#employees)=60/6=10units per employee
(%sales) / employee=(units per employee)/(total units)
=(10/124)x100
=(8.06%) / employee
Team2 sales percentage=(8.06%)x6 employees
=48.39% of total sales
Note: This percentages could have been found by simply
dividing (Team2 total #units) / (total #units)
dividing (Team2 total #units) / (total #units)
Both team sales percentages do add up to 100% of total
sales. Team1 had the better "team sales percentage"
at 51.61% and would be declared the winner.
