Answer 1

Rebecca's energy level and score after three turns in a video game, including whether she earned bonus points.

Step-by-step explanation:

1. Using only addition, Rebecca's score after these three turns can be expressed as: 4 - 6 + 8 - 1 = 5.

2. Rebecca's energy level after turn 1 is 4 - 6 = -2.

3. Rebecca's energy level after turn 2 is -2 + 8 = 6.

After turn 3, Rebecca's energy level is 6 - 1 = 5. She will not earn bonus points because she needs to reach level 10 to earn the bonus points.
