If Benjamin's salary of $4,100 per month is increased by 12%, what is his new monthly salary?
To calculate Benjamin's new monthly salary after a 12% increase, you would first multiply his current salary by 12%:
$4,100 x 0.12 = $492
Then, add this amount to his current salary:
$4,100 + $492 = $4,592
Therefore, Benjamin's new monthly salary after a 12% increase would be $4,592.
