Markos

Jennie

Correct


How much more? $

To determine how much more Markos makes compared to Jennie, let's break down the key information from the boxplot description:

1. **Jennie (Construction Worker) makes the first quartile salary**: 
   From the construction worker boxplot:
   - The first quartile (Q1) is given by the left edge of the box, which is at $40,000.

2. **Markos (Teacher) makes the third quartile salary**:
   From the teacher boxplot:
   - The third quartile (Q3) is given by the right edge of the teacher’s box, which is at $50,000.

Now, to find how much more Markos makes than Jennie:
\[
50,000 - 40,000 = 10,000
\]

**Answer**: Markos makes **$10,000** more than Jennie.
