Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
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.

### Response:
 Ikiwa kulikuwa na wanachama 150 katika kikundi kabla ya msimamizi kuwaondoa 20, basi wanachama 150-20 = 130 walibaki baada ya 20 kuondolewa.
Wanachama wa kikundi kila mmoja waliposti ujumbe 50 kwa siku, jumla ya ujumbe 50*130 = <<50*130=6500>>6500.
Kwa wiki, na siku saba, wanachama wa kikundi wangepeleka ujumbe 6500*7 = <<6500*7=45500>>45500.
