Question

PLEASE HELP!!!!! My volleyball team plays three games a week. In the first four weeks, my team lost all 12 of our games. In the fifth week, my team won two games and lost one game, bringing us to 2 wins and 13 losses. Each week after that, my team won two games and lost one game. At the end of which week will my team have won at least 60% of its games?

Answer 1

Answer:

Step-by-step explanation

Wins: 2+2x

Losses:13+x

$\frac{2+2x}{13+1x}=\frac{6}{10}$

20+20x=78+6x

58=14x

x=58/14

x=4$\frac{1}{7}$

5 weeks

Answer 2

After week 5, the record is 2 wins and 13 losses.

After week 6, the record is 4 wins and 14 losses.

After week 7, the record is 6 wins and 15 losses.

If we keep going with this pattern, then after 37 weeks, there will be 66 wins and 44 losses, so the percentage win is 66/(66 + 44) = 60%.

So the answer is 37.
