Answer:
$6540.
Explanation:
We have been given that a personal trainer makes $25000 per year and has just begun contributing 6% of his salary to his 401k plan.
Let us find trainer's contribution to 401k plan by calculating 6% of $25,000.
As his employer matches 9% of his contribution, so amount contributed by employer to trainer's 401k plan per year will be 9% of 1500.


To find the amount contributed to the 401k plan after 4 years, we will multiply $1635 by 4.


Therefore, $6540 will have been contributed to the 401k plan after 4 years.
