Question

Erin needs to make at least a 75 on her semester exam to maintain a B in the class. Which number line correctly represents this situation?

A.
B.
C.
D.

Answer 1

C

Explanation:

"At least 75" means Erin needs a score that is 75 or more. Her score should be equal to or greater than 75.

The number line that shows this is C because the point at 75 is filled in (showing that 75 is included), and the ray (arrow) extends to the right indicating numbers larger than 75.
