Lizzy: After violating the group's policies, 20 members of a Facebook group were removed by the group's admin. If each member posted 50 messages per day in the group and the number of members in the group was 150 before the admin removed some, calculate the total number of messages the remaining members would send in a week..
Me: Hmmm, let me think. I think this is the detailed solution:
If there were 150 members in the group before the admin removed 20, then 150 - 20 = 130 members remained after 20 were removed. The group members each posted 50 messages in a day, a total of 50 * 130 = 6500 messages. In a week, with seven days, the group members would have posted 6500 * 7 = 45500 messages. Final answer: 45500.
