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

### Instruction:
Matt needs to buy new plates for his home.  He only wants to do dishes once a week.  Three days a week it is only him and his son eating and they use 1 plate each.  On the remainder of the days, his parents join them and everyone uses 2 plates that day.  How many plates does he need to buy?

### Response:
 Kwa hivyo kwa siku 3, kuna watu 1+1=2 wanaokula. Kwa hivyo siku hizo hutumia sahani 2*3=<<2*3=6>>6. Kwa siku 7-3=<<7-3=4>>4, wazazi wake wanajiunga nao. Kwa siku hizo kuna watu 2+2=<<2+2=4>>4 wanaokula. Hutumia sahani 4*2=<<4*2=8>>8. Kwa hivyo hutumia jumla ya sahani 8*4=<<8*4=32>>32. Hii inamaanisha jumla ya sahani wanazotumia ni 32+6=<<32+6=38>>38.
