Answer:
Team A scored 64 points
Explanation:
If both the teams scored 146 points we can do 146/2 to find what the score would have been if they scored the same. This is 73 per team but team A scored 18 points less so we do 73-9 (for team a) and 73+9(for team b). 73-9 is 64 so Team A scored 64 points. (Sorry if this is messy)
