Answer:
The difference in their thickness is: [tex]2\frac{1}{2}[/tex]
Step-by-step explanation:
Given
The attached plot which represents thickness of books
Required
Difference in the thickness of Amalie's (A) and Raj's (R)
From the question, we understand that:
[tex]A \to[/tex] Thickest
[tex]R \to[/tex] One of the least
This implies that:
[tex]A = 4[/tex]
[tex]R = 1\frac{1}{2}[/tex]
The difference (d) is:
[tex]d = 4 - 1\frac{1}{2}[/tex]
[tex]d = 2\frac{1}{2}[/tex]
