Final answer:
The Adams High School girls' softball team must win at least 9 of the remaining 16 games to finish the season with a winning record.
Step-by-step explanation:
In order to finish the season winning more than 50% of all the team's games, the softball team must win more than half of the total number of games they play. The team has played 17 games so far (10 wins + 7 losses), and there are 16 games remaining. To determine the least number of games they must win, we need to find the number of wins needed that will result in winning more than 50% of their total games. Since 50% of the total games would be 16.5 (33 games), the team must win at least 9 of the remaining 16 games to have a winning record.
