Answer:
C) The arrow points to 76.5.
Explanation:
The number line is divided into 10 parts equally.
We can find out the distance between each point by taking the difference between the largest and smallest number on the number line and dividing the difference by 10.
80 - 75 = 5
5/10 = .5
So, the distance between each number/mark on the line is .5
Now, we can label each point by adding .5 to each mark as we go. Then, we'd get this.
*see attachment below
Since the number line constructed here has all the values, we can now tell which value the arrow is pointing to.
The answer is therefore 76.5.
