A box plot is a graphical representation of the five number summary;
The minimum, first quartile, median, third quartile, and the maximum value in that order.
The IQR is defined as;
third quartile - first quartile
With this definition, the Interquartile Range (IQR) for Florida is;
28 - 17 = 11
while the Interquartile Range (IQR) for Australia is;
14 - 10 = 4
Therefore, the Interquartile Range (IQR) for Florida, 11, is greater than the IQR for Australia, 4.

9 - (a - 7)
Note that - = -1
First, distribute - 1 to all terms within the parenthesis
-1(a - 7) = -a + 7
9 - a + 7
Combine like terms
9 + 7 = 16
-a + 16, or A. 16 - a is your answer
hope this helps
