Answer 2

We are given with the number of pounds for serving size as a table.

To know which value has error, let us find ratio of serving size to pounds of meat for 4 given rows.

Ratio for serving size 20 =
`(20)/(2.5) =8`

Ratio for serving size 50=
`(50)/(6.5) =7.6923`

Ratio for serving size 80 =
`(80)/(10) =8`

Ratio for serving size 120 =
`(120)/(15)=8`

Clearly we can see that ratio for serving size 50 is different from other three ratios.

Hence the employee made an error for 50 serving size.
