To determine how many shifts Dr. Lewis worked in March, we need to establish her total shifts in February first. The question states that Dr. Lewis worked half the number of shifts in March compared to February.

If we denote the number of shifts she worked in February as \(x\), then the number of shifts she worked in March would be \( \frac{x}{2} \).

For the answer to be 10 shifts in March, the calculation implies that Dr. Lewis would have worked 20 shifts in February, because half of 20 is 10. Thus, this answer fits perfectly with the relationship described in the question.

By isolating this relationship and confirming the calculations, we can see that choosing 10 shifts for March means she worked a total of 20 shifts in February, satisfying the condition provided.
