18.18%

Explanation:

Answer 2

18.18%

Explanation:

-Percent error is defined as the deviation as a percentage of the actual value.

#Given the actual sold units is 110 and the predicted is 90, the percent error can be calculated as:

`\bigtriangleup=110-90\\\\=20\\\\\therefore \% \bigtriangleup=(20)/(110)\\\\=0.1818 \ \ or \ \ \ 18.18\%`

Hence, the perecent error is 18.18%
