Layla had the higher score by 20 points.
Step-by-step explanation:
Given,
Points for correct answer = 10 points
Points for incorrect answer = 20 points
Loss means subtraction;
Therefore,
Total points of Ji = Correct answers*10 - Incorrect answers*20
Total points of Ji = 7*10 - 3*20
Total points of Ji = 70 - 60
Total points of Ji = 10 points
Total points of Layla = Correct answers*10 - Incorrect answers*20
Total points of Layla = 5*10 - 1*20
Total points of Layla = 50 - 20
Total points of Layla = 30 points
Difference = Points of Layla - Points of Ji
Difference = 30 - 10 = 20 points
Layla had the higher score by 20 points.
