20,000+20(20,000)+20(500)=x
20,000+400,000+10,000=x
430,000=x
430,000/20=21,500
total salary=$430,000
mean annual salary=$21,500

We respect everybody here, but there's no harm in trying this one:
Total years working= years
1st year earnings: $20,000
2nd year: $20,500..... adding $500 after the 1st year
So we can arrive to an eqn:
------> total salary
where = no. of years. Why there's (-1) in the eqn? Because the increased started on the 2nd year. Continuing,
$409,500 ------------------------> Total salary.
For Mean Salary:
= $20,475 --------> Mean salary
Thank you,
Jojo
