The correct statement that best describes Simone's error is: **Simone did not use the greatest common factor in the equation.**
In the given expression \(28 + 60\), the greatest common factor (GCF) of both numbers is 4, but her work shows \(4(7 + 20)\) which is incorrect as it doesn't represent the original sum correctly. Instead, it should have accurately factored \(4\) out from both \(28\) and \(60\) as:
\[ 28 + 60 = 4(7 + 15) \]
Thus, her expression does not reflect the correct use of the GCF.
