Our basketball team has finished 80% of its season, during which we won 40% of the games we played. What percent of the remainder of our games must we win in order to finish the season with the same number of wins as losses?

So far they have played 80% and won 40% of those that is 0.8*0.4 = 32% won so far

 

32% + 20% of x% = 50%

0.32 +  0.2*0.01x = 0.5

0.002x = 0.5-0.32

0.002x = 0.18

x= 180/2 = 90

 

So we must win 90% of the remaining games.
