Problema Solution
In order to qualify for a company pension plan, an employee must average at least $1000 per month in earnings. During the first four months of the year, an employee made $900, $1200, $1040, and $760. What amount of earnings during the fifth month will qualify the employee for the pension plan?
Answer provided by our tutors
The five-month average has to equal $1000.
You know four of the months and the fifth month is X.
(900+1200+1040+760+X)/5 = 1000
(3900+X)/5=1000
3900+X = 5000
X= 5000-3900
X= 1100 = $1100 in the fifth month.
