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

### Instruction:
 Allen alinunua masanduku matano ya pizza, ambayo kila moja inagharimu $7. Kisha alitoa kitita cha asilimia 1/7 ya gharama yote ya agizo lake kama bahshishi. Ikiwa alimpa mfanyakazi wa kumfikishia pizza $100, alipokea pesa ngapi kama mabadiliko?


### Response:
 Allen alitumia 5 x $7 = $<<5*7=35>>35 kwa masanduku matano ya pizza.
Alitoa bahshishi ya $35 x 1/7 = $<<35*1/7=5>>5 kwa mfanyakazi wa kumfikishia pizza.
Na, alitumia jumla ya $35 + $5 = $<<35+5=40>>40 kwa pizza na bahshishi.
Mabadiliko aliyopokea ni $100 - $40 = $<<100-40=60>>60.
