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

### Instruction:
 Bi. Petersons alinunua glasi 10 kwa $45 kila moja. Aliwalipa kwa noti tano za $100. Bi. Petersons atapokea kiasi gani cha pesa kama mabadiliko?


### Response:
 Glasi 10 zina thamani ya $45 x 10 = $<<45*10=450>>450.
Noti tano za $100 za Bi. Petersons zina thamani ya $100 x 5 = $<<100*5=500>>500.
Hivyo, mabadiliko yake yatakuwa $500 - $450 = $<<500-450=50>>50.
