Understanding Book Price Inequalities

Mrs. Nelson explains how to write and graph inequalities using a book sale scenario where books cost less than $5. She demonstrates writing an inequality to represent the situation and graphing it on a number line, ensuring to indicate that book prices are greater than $0 and less than $5. The lesson emphasizes understanding the representation of inequalities and graphing them accurately.

What is the main objective of the lesson on writing and graphing inequalities?

• To understand multiplication

• To learn about fractions

• To write and graph inequalities

• To solve complex equations

In the problem statement, what is the maximum price a book can be at the sale?

• $5.00

• $4.50

• $4.99

• $5.01

Which variable is used to represent the cost of books in the inequality?

• C

• B

• A

• D

What is the inequality used to represent the cost of books at the sale?

• B > 5

• B < 0

• B < 5 and B > 0

• B = 5

How is the number 5 represented on the number line when graphing the inequality?

• With a triangle

• With a circle around it

• With a filled dot

• With a square

Why can't the book prices include values like $1.52?

• Because they are not exact cent values

• Because they are too cheap

• Because they are too expensive

• Because they are not whole numbers

What does the solid line between 0 and 5 on the number line indicate?

• Only whole numbers are acceptable

• Only odd numbers are acceptable

• All values are acceptable

• Only even numbers are acceptable

What is the significance of using dots on the number line?

• To show only whole numbers

• To show only even numbers

• To show only odd numbers

• To show every 1 cent value

What is the correct representation of the inequality on a number line?

• A line from 0 to 5 with no markings

• A line from 0 to 5 with squares

• A line from 0 to 5 with circles at 0 and 5

• A line from 0 to 5 with filled dots

What does the lesson conclude about the representation of book prices?

• They can be any value

• They must be exact cent values

• They must be whole numbers

• They must be even numbers
