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

### Instruction:
A van is delivering  180 bottles of drinks to a neighborhood, and each bottle contains either cider or beer or a mixture of two. Out of the  180 bottles, 40 contain only cider, 80 contain only beer, and the rest are a mixture of the two drinks. If the delivery man gives half the number of each bottle of drink to the first house, how many bottles does the first house get?

### Response:
 Jumla ya chupa ni 180.
Idadi ya chupa zinazotia ndani cider ni 40.
Idadi ya chupa zinazotia ndani bia ni 80.
Idadi ya chupa zinazotia ndani mchanganyiko wa cider na bia ni 180 - 40 - 80 = 60.
Idadi ya chupa za cider ambazo nyumba ya kwanza inapata ni 40 / 2 = 20.
Idadi ya chupa za bia ambazo nyumba ya kwanza inapata ni 80 / 2 = 40.
Idadi ya chupa zinazotia ndani mchanganyiko wa cider na bia ambazo nyumba ya kwanza inapata ni 60 / 2 = 30.
Jumla ya idadi ya chupa ambazo nyumba ya kwanza inapata ni 20 + 40 + 30 = <<20+40+30=90>>90.
