During a certain season, a team won 80 percent of its first 100 games and 50 percent of its remaining games. If the team won 70 percent of its games for the entire season, what was the total number of games that the team played?

During a certain season, a team won 80 percent of its first 100 games and 50 percent of its remaining games. If the team won 70 percent of its games for the entire season, what was the total number of games that the team played?

(A) 180 (B) 170 (C) 156 (D) 150 (E) 105

This is simple weighted average question.

Let the # of the remaining games be \(x\) then \(0.8*100+0.5*x=0.7*(100+x)\) --> \(x=50\) --> total # of games thus equal to \(100+x=100+50=150\).

Total # of games = x # of games won in first 100 = .8 * 100 # of games won in remaining games = .5 * (x-100) # of games won in entire season = .7x

During a certain season, a team won 80 percent of its first 100 games and 50 percent of its remaining games. If the team won 70 percent of its games for the entire season, what was the total number of games that the team played?

(A) 180 (B) 170 (C) 156 (D) 150 (E) 105

If we let G = the TOTAL number of games played in the ENTIRE SEASON, then ... G - 100 = the number of games REMAINING after the first 100 have been played

We can now start with a "word equation": (# of wins in 1st 100 games) + (# of wins in remaining games) = (# of wins in ENTIRE season) We get: (80% of 100) + (50% of G-100) = 70% of G Rewrite as 80 + 0.5(G - 100) = 0.7G Expand: 80 + 0.5G - 50 = 0.7G Simplify: 30 = 0.2G Solve: G = 150

During a certain season, a team won 80 percent of its first 100 games and 50 percent of its remaining games. If the team won 70 percent of its games for the entire season, what was the total number of games that the team played?

(A) 180 (B) 170 (C) 156 (D) 150 (E) 105

Given: A team won 80 percent of its first 100 games and 50 percent of its remaining games. Team won 70 percent of its total games Required: Total number of games played?

Assume that the remaining games = 100x Total games won = 80 + 50x This is 70% of the total games played.

During a certain season, a team won 80 percent of its first 100 games and 50 percent of its remaining games. If the team won 70 percent of its games for the entire season, what was the total number of games that the team played?

(A) 180 (B) 170 (C) 156 (D) 150 (E) 105

We are first given that a team won 80 percent of its first 100 games. This means the team won 0.8 x 100 = 80 games out of its first 100 games.

We are next given that the team won 50 percent of its remaining games. If we use variable T to represent the total number of games in the season, then we can say T – 100 equals the number of remaining games in the season. Thus we can say:

0.5(T – 100) = number of wins for remaining games

0.5T – 50 = number of wins for remaining games

Lastly, we are given that team won 70 percent of all games played in the season. That is, they won 0.7T games in the entire season. With this we can set up the equation:

Number of first 100 games won + Number of games won for remaining games = Total Number of games won in the entire season

80 + 0.5T – 50 = 0.7T

30 = 0.2T

300 = 2T

150 = T

Answer is D.

The difference between these numbers are in blue, above.

The ratio of the initial set (100 games) and the second set (x games) will be: 100/x = 20/10. Thus x = 50. Total number of games played = 100 + x = 150
