Question 1209083
<font color=black size=3>
n = number of games in the entire season


Your team has played 0.6n games so far.
0.9*0.6n = 0.54n = number of games won.
n-0.54n = 0.46n = number of games lost.


There are n-0.6n = 0.4n games remaining.


Let x be a number between 0 and 1 such that it represents the decimal form of the percentage of games to win from here on out.
For example, if x = 0.2 then it means you need to win 20% of the remaining games.


x*0.4n = number of additional games to win


Add up the wins and set them equal to the number of losses.
0.54n + x*0.4n = 0.46n
0.54 + x*0.4 = 0.46
If you solved for x, you would get x = -0.2
Since it's not between 0 and 1, it appears your teacher has made a typo when setting up this problem.
