Answer 1

Given

• Initial score = 15 points,
• First turn = 15 points loss,
• Second turn = 20 points loss.

Part A

The change in score can be shown as:

• 15 - 15 - 20

On the number line we'll get:

• 15 → 0 → - 20

And the points marked are:

• - 20, 0, 15

Part B

The final score is:

• 15 - 15 - 20 =
• - 20
