Answer:
D. 1.30
Step-by-step explanation:
As you can see on the number line, since there are 10 markings between the marks of 1 and 2, we can divide that to get the value that each marking represents.
Hence, each marking represents a change of [tex]\frac{2 - 1}{10}[/tex], which would equal to [tex]\frac{1}{10}[/tex].
Therefore, A would be 1 + (3 [tex]\cdot[/tex] [tex]\frac{1}{10}[/tex]), which equals to 1.3.
(As for why it would be 1 + (3 [tex]\cdot[/tex] [tex]\frac{1}{10}[/tex]), that is because we can deduce the number line grows as it goes to the right due to the main markings (0, 1, 2) also growing as they go towards the right.)
Hope this helped!
