If the team won 40% of its first 15 games then the number of the winning games was: 15 * 0.4 = 6. Therefore the team lost 15 - 6 = 9 games.

So the number of the lost games stays the same while the team wins new games in the row. They have to achieve 55% wins, so 100% - 55% = 45% is the new percent of lost games.

x * 0.45 = 9

x = 9 : 0.45

x = 20

20 - 15 = 5

Answer: The team have to win 5 games in a row in order to have 55%

winning record.
