Answer:
28 : 35
Step-by-step explanation:
Total number of points = 63
Team A scores 80% of the number of points that Team B scores.
If team B scores x, that means Team A scores 0.8x
Team A scores + Team B scores = 63
Substitute the values;
0.8x + x = 63
1.8x = 63
x = 63 / 1.8 = 35
Team B = 35
Team A = 28
Final score of the game is;
Team A : Team B
28 : 35
