Define a variable and write an inequality. Then solve. A local summer basecall team plays 20 games each season. So far, they have won 9 games and lost 2. How many more games much they win this season to win at least 75% of all their games?
Just think through the problem.
They have played 11 games and have 9 left. They need to win 15 or more in the season. They have won 9 already. Therefore they need to win 6 or more of the remaining games to win at least 15.
X >or= 6
if X is the number of future games that must be won (out of 9 to be played).
