Question

Alicia estimated that the number of horses living in a stable was 26. The actual number of horses living in the stable was 30.

Answer 1

$\%\text{error}=\dfrac{|\text{estimated value}-\text{actual value}|}{\text{actual value }}\cdot100\%\\\\ \%\text{error}=\dfrac{|26-30|}{30}\cdot100\%\\ \%\text{error}=\dfrac{|-4|}{30}\cdot100\%\\ \%\text{error}=\dfrac{4}{30}\cdot100\%\\ \%\text{error}\approx13\%$
