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

### Instruction:
James visits 20 houses to try and make a sale.  He manages to sell something in every house.  The next day he visits twice as many houses but only sold to 80% of houses.  If he sold two things at each house in each of the two days, how many items did he sell?

### Response:
 Siku ya pili alitembelea nyumba 20*2=<<20*2=40>>40
Hivyo aliuza vitu katika nyumba 40*.8=<<40*.8=32>>32
Jumla ya vitu alivyoviuza ni 20+32=<<20+32=52>>52 nyumba
Hivyo aliuza vitu 52*2=<<52*2=104>>104
