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

### Instruction:
Peter and his dad Rupert shared the same birthday.  To make it special, they each got their own birthday cake.  Peter has 10 candles on his cake.  Rupert is 3 and 1/2 times older than Peter.  How many candles will be on Rupert's cake?

### Response:
 Kwa kuwa Peter ana umri wa miaka 10 na Rupert ni mara 3.5 zaidi, basi Rupert atakuwa na umri wa 10*3.5 = <<10*3.5=35>>35 miaka.
Hivyo, Rupert atakuwa na mishumaa 35 kwenye keki yake.
