Lizzy: 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?.
Me: Hmmm, let me think. I think this is the detailed solution:
He played 7 * 2 = 14 gigs. The long song was 5 * 2 = 10 minutes. So all the gigs were 5 + 5 + 10 = 20 minutes. So he played 14 * 20 = 140 minutes. Final answer: 280.
