The box plot represents the minimum, maximum, the first quartile, the second quartile and the median.
If we look at the breakfast box plot, the median is 150 calories
When we look at the afternoon lunch box plot, the median 375 (the dot is between 350 and 400)
So breakfast = 150 calories
Lunch = 375 calories
So difference = 375 -150 = 225 calories.
Therefore George's lunch has 225 calories more than breakfast
Answer is 225
