At a firm, ten entry-level employees earn $40,000 a year, 6 junior-level employees earn $60,000 a year, and 3 managers earn $80,000 a year per person respectively. Find the weighted average of the firm.

answer is: 1000000/19

Step-by-step explanation:

10/19 - 40k -> 10/19*40k= 400000/19

6/19- 60k -> 6/19*60k= 360000/19

3/19 - 80k -> 3/19*80k=240000/19

400000/19+360000/19+240000/19=1000000/19

answer is: 1000000/19
