Just compare the change in unit cost to the original unit cost.
Shovels: (70.38 ÷ 2 - (172.50/5) ÷ (172.50/5) = 0.02
Salt: (26.04 ÷ 4 - (6.20) <span>÷ </span>6.20 = 0.05
So, the shovels went up 2% and the salt went up 5%

<h3>
Answer: Choice B) 0.5</h3>
=============================================================
Explanation:
For now, focus solely on the orange boxplot. The first quartile Q1 is the left edge of the box, which is at 3.5; while the value of Q3 is 7.5 (right edge of the box). The interquarile range (IQR) is ...
IQR = Q3 - Q1
IQR = 7.5 - 3.5
IQR = 4
This is basically the width of the box. Ignore the whiskers when it comes to the IQR.
Let A = 4 as we'll use it later.
---------------------------------
Find the IQR for the blue box plot
Q1 = 6 = left edge of the blue box
Q3 = 9.5 = right edge of the blue box
IQR = Q3 - Q1
IQR = 9.5 - 6
IQR = 3.5
Let B = 3.5 as we'll use it later
---------------------------------
Subtract the values of A and B to find the difference of the IQR values
A - B = 4 - 3.5 = 0.5
