In a basketball league, the Falcons won 15 of their first 20 games. If they win only half the time from now on, how many more games will they have to play in order to win 60% total games?

Answer 1

15 + n/2 3

--------------- = ----

20 + n 5

5 ( n/2 + 15) = 3(20 + n)

(5/2)n + 75 = 60 + 3n

75 - 60 = 3n - (5/2)n

15 = (1/2)n

30= n

15 + 15

--------- = 30/50 = 3/5

20+30

The need to play 30 more games.
