Answer
$\$2950$ per month
Work Step by Step
We are given the arithmetic mean which is $\$3210$ and we know one employee earns $\$3470$ so we have to find the other employee's salary using the arithmetic mean formula:
Arithmetic mean=$\dfrac{x+y}{2}$ where $x$ represents one employee's salary and $y$ represents the other employee's salary.
$3210=\dfrac{3470+y}{2}$
$3210(2)=3470+y$
$6420=3470+y$
$6420-3470=y$
$2950=y$
Thus, the other employee earns $\$2950$ per month.
