A team won 40 percent of its first 30 games in a particular season, and 80 percent of its remaining games. If the team won a total of 70 percent of its games that season, what was the total number of games that the team played?  Choose the correct option:
A) 60
B) 90
C) 120
D) 150
E) 180
70% is 30%-points above 40% and 10%-points below 80%.   Thus the ratio of "the first 30 games" to "remaining games" is 1:3.   So the team played a total of 30+90=
