### Instruction:
 Thomas anataka kuandaa sherehe kwa ajili ya rafiki yake bora Casey. Anahitaji kuagiza viti vya kutosha kwa wageni wote wa sherehe waweze kukaa, kimoja kwa kila mgeni. Kwanza anaagiza viti 3 dazeni kwa ajili ya wageni 3 dazeni anaowaalika. Kisha anagundua kuwa 1/3 ya wageni wanataka kuja na mgeni wao, hivyo Thomas anahitaji kuagiza viti zaidi. Hatimaye, Thomas anagundua kuwa wageni 5 kati ya wale aliowaalika awali hawawezi kufika. Thomas pia anataka kuagiza viti 12 ziada kwa ikiwa watavihitaji. Thomas atahitaji viti vingapi kwa sherehe ya Casey?



### Response:
 Thomas anaanza kwa kuagiza viti kwa ajili ya wageni 3 dazeni, 12 x 3 = 36 wageni.
Thomas anagundua kuwa 1/3 ya wageni wanataka kuja na mgeni wao, 1/3 ya 36 = 12.
Wageni hao 12 wanakuja na mgeni wao mmoja kila mmoja, 36 wageni + 12 wageni = <<36+12=48>>48.
Thomas anagundua kuwa wageni 5 kati yao hawawezi kufika, 48 wageni - 5 wageni = <<48-5=43>>43.
Thomas anataka kuagiza viti ziada 12, 43 + 12 = <<43+12=55>>55.
Thomas atahitaji viti 55 kwa sherehe.
