7
3

Explanation:

Step1: Calculate the total score

To find the total score, we need to add the scores of each round. The scores are -4 (Round 1), 9 (Round 2), and -2 (Round 3).

$$\begin{align*} \text{Total score}&=-4 + 9+(-2)\\ \end{align*}$$

Step2: Simplify the addition

First, add -4 and 9: $-4 + 9=5$. Then add -2 to the result: $5+(-2)=3$.

$$\begin{align*} -4 + 9+(-2)&=( -4 + 9)-2\\ &=5-2\\ &=3 \end{align*}$$

Answer:

E. 3
