Can anyone help me solve this statistics question?

A small company has a limited budget for salaries. It can afford to pay an average of $35,000 a year to its employees. If the first 5 employees are paid $37,000, $38,000, $33,000, $39,000 and $29,000, then how much money can they pay the sixth employee without exceeding their budget?

I have tried to figure it out and I keep getting the wrong answer.

Thanks!
