Lizzy: Jason sent 220 text messages on Monday, half as many text messages on Tuesday, and 50 text messages each day Wednesday through Friday. How many text messages did he send on average during those five days?.
Me: Hmmm, let me think. I think this is the detailed solution:
First find how many text messages he sent on Tuesday: 220 messages / 2 = 110 messages. Then find how many text messages he sent Wednesday - Friday: 50 messages / day * 3 days = 150 messages. Then add up all the messages he sent to find the total: 110 messages + 150 messages + 220 messages = 480 messages. Then divide that number by the number of days to find the average number of messages he sent per day: 480 messages / 5 days = 96 messages / day. Final answer: 96.
