Answer 1

EXPLANATION:

We are given a number line which is also used to indicate the points scored by players in a game.

For each round which is represented by;

Blue (Round1)

Green (Round2)

Red (Round3)

We can tell Eric's scores as shown on the number line as follows;

$\begin{gathered} \text{Round}1=-20-(-10) \\ \text{Round}1=-20+10 \\ \text{Round}1=-10 \end{gathered}$$\begin{gathered} \text{Round}2=20-(-20) \\ \text{Round}2=20+20 \\ \text{Round}2=40 \end{gathered}$$\begin{gathered} \text{Round}3=-10-0 \\ \text{Round}3=-10 \end{gathered}$

Therefore, Eric's score for each round is summarized as follows;
