Explanation:

Step1: Find Jennie's salary

Jennie's salary = min of Construction: ~25k (from boxplot left whisker)

Step2: Find Markos's salary

Markos's salary = Q3 of Teacher: ~40k (boxplot right edge)

Step3: Compare salaries

40k > 25k → Markos makes more.

Step4: Calculate difference

40k - 25k = 15k → 15000 dollars.

Answer:

Markos makes more money. The difference is 15000 dollars.
