Question

In the first round of a card game, Niki scored 20 points. Then, she lost 10 points on one turn and an additional 25 points on her final turn.

a) 0→−20→−10→15
b) 20→0→−10→15
c) 0→20→−5→5
d) 0→20→10→−15

Answer 1

The correct choice that represents the sequence of score changes for Niki in the card game is 0 (start), then 20 (after gaining points), followed by 10 (after losing points), and finally -15 (after losing more points).

Step-by-step explanation:

The subject of this question is Mathematics, as the student is tasked with understanding a sequence of score changes in a card game, which involves basic arithmetic operations like addition and subtraction.

Niki starts a card game with 0 points. After the first round, she scores 20 points, so her score becomes 0 + 20 = 20. Then, she loses 10 points, changing her score to 20 - 10 = 10. Finally, she loses an additional 25 points, and her score changes from 10 to 10 - 25 = -15.

Therefore, the correct sequence of Niki's score during the game is:

• 0 (starting score)
• 20 (after scoring 20 points)
• 10 (after losing 10 points)
• -15 (after losing an additional 25 points)
