Since 1 year has
[tex]1\text{year}=8760\text{ hours}[/tex]Therefore, in 1 year, he/she will earn
[tex]13\times8760[/tex]which is equal to $113,880.
Since employee works 71 years, he/she will earn
[tex]71\times113880[/tex]which is equal to $8,085,480

[tex]\frac{143,100,000,000}{8085480}[/tex]which is equal to 17,698.39. This means that the employee will take 17,698 lifes to earn Jeff Bezos money.
