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

### Instruction:
Allen ordered five boxes of pizza, which cost $7 each box. He then gave a tip which amounts to 1/7 of the total cost of his order. If he gave the delivery man $100, how much change did he receive?

### 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.
