Question

A set of books sits on a shelf at a store. This line plot

Answer 1

Answer:

The difference in their thickness is: $2\frac{1}{2}$

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:

$A \to$ Thickest

$R \to$ One of the least

This implies that:

$A = 4$

$R = 1\frac{1}{2}$

The difference (d) is:

$d = 4 - 1\frac{1}{2}$

$d = 2\frac{1}{2}$
