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

### Instruction:
Carl buys index cards for his class.  He gives each student 10 index cards.  He teaches 6 periods a day and each class has 30 students.  If a 50 pack of index cards cost $3 how much did he spend on them all?

### Response:
 Anafundisha wanafunzi 6*30=<<6*30=180>>180 kwa siku
Hivyo anahitaji kadi za indeksi 180*10=<<180*10=1800>>1800
Hii inamaanisha anahitaji kununua pakiti 1800/50=<<1800/50=36>>36 za kadi za indeksi
Hivyo anatumia 36*3=$<<36*3=108>>108 kwa kadi za indeksi
