(Total Wins)/(Total Games) = 0.750

15+9 = 24

24 is 16 2/3% of what?

anonymous · Answer

144...?

tkhunny · Answer

144/6 = 24 -- Correct.

How many games must be won in total - forgetting that some already have been played?

anonymous · Answer

144?

tkhunny · Answer

No, only 75% of 144 is required.  No one wins ALL their games!

anonymous · Answer

36?

tkhunny · Answer

What is 36?  36 is certainly not 75% of 144.

anonymous · Answer

Oh wait..I subtracted by accident. 108?

tkhunny · Answer

144*0.75 = 108 -- Correct.

Now the question is, how many games must the win from the remaining games in order to get to 75%?

They already have 15 wins and they need 108 total.

93

tkhunny · Answer

How many games are left?

tkhunny · Answer

I ask this additional question only because there had better be at least 93 games remaining.  If there are only 85 games remaining, it is VERY DIFFICULT to win 93 of them.

anonymous · Answer

Um...93..?

tkhunny · Answer

144-15-9 = 120

93/120 = 0.775 <== They need to win a lot of games from now on.
