Question

Rebecca is playing a video game that involves planting and cutting down trees. She moves up an energy level for each tree she plants, and she moves down a level for each tree she cuts. If Rebecca reaches energy level 10, she will earn bonus points.

Rebecca is currently at energy level 4. The results of her next 3 turns are:
Turn 1: 6 trees cut
Turn 2: 8 trees planted
Turn 3: 1 tree cut
Answer the questions to find out whether Rebecca earned bonus points in the next 3 turns. Use the number line to help you add.

2. What is Rebecca's energy level after Turn 1? (2 points)

3. What is Rebecca's energy level after Turn 2? (3 points)

Answer 1

5

Step-by-step explanation: I think this because 4 - 6 is -2 and -2 + 8 is 6 - 1 is 5

Answer 2

Answer: Her energy level after turn one is -2. Her energy level after turn 2 is 5. She did not reach level 10, therefore she did not earn bonus points.

Step-by-step explanation:

Starting level: 4

Turn one: 4-6, so by the end of turn one she’s at level -2.

Turn two: -2 + 8 = 6, so by the end of turn two she reaches level 6.

Turn three: 6-1 = 5, so by the end of those three turns she’s at level 5.
