Answer :

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
