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

### Instruction:
Andrew's father buys a package of 100 masks. Andrew lives with his 2 parents and 2 siblings. All members of Andrew's family change masks every 4 days. How many days will it take to finish the pack of masks?

### Response:
 Familia ya Andrew ina watu 1 + 2 + 2 = <<1+2+2=5>>5.
Kila mtu akivaa barakoa kila baada ya siku 4, barakoa zitadumu 100 barakoa / 5 watu = 20 barakoa kwa kila mtu.
Kwa 20 barakoa kwa kila mtu, barakoa zitadumu 20 barakoa/mtu * 4 siku/barakoa = 80 siku.
