Mark does a gig every other day for 2 weeks.  For each gig, he plays 3 songs.  2 of the songs are 5 minutes long and the last song is twice that long.  How many minutes did he play?
He played 7*2 = <<7*2=14>>14 gigs
The long song was 5*2=<<5*2=10>>10 minutes
So all the gigs were 5+5+10=<<5+5+10=20>>20 minutes
So he played 14*20=140 minutes
