Michelle's score is given by the following formula

$S=2\cdot C$

where, S is her final score and C represent the number of correct answers.

Since she must get at least a 92, then S = 92

therefore,

$\begin{gathered} 92=2\cdot C \\ C=(92)/(2) \\ C=46 \end{gathered}$

She must get at least 46 correct questions.
