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

### Instruction:
 Sean na Sierra walialika wageni 200 kwenye harusi yao. Ikiwa 83% ya wageni walijibu kwa Ndiyo na 9% ya wageni walijibu kwa Hapana, wageni wangapi hawakujibu kabisa?


### Response:
 Sean na Sierra walipokea majibu ya Ndiyo ya 200 x 83% = <<200*83*.01=166>>166.
Walipokea majibu ya Hapana ya 200 x 9% = <<200*9*.01=18>>18.
Bado wanangojea majibu ya 200 - (166 + 18) = <<200-(166+18)=16>>16.
