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

### Instruction:
 Angela ni mrefu kwa cm 4 kuliko Helen. Helen ni mrefu kwa cm 3 kuliko Amy. Ikiwa Amy ana urefu wa cm 150, Angela ana urefu wa cm ngapi?


### Response:
 Urefu wa Amy ni <<150=150>>150 cm. 
Ikiwa Helen ni mrefu kwa cm 3 kuliko Amy, basi urefu wake ni 150 + 3 = <<150+3=153>>153 cm. 
Kwa kuwa Angela ni mrefu kwa cm 4 kuliko Helen, basi Angela ana urefu wa 153 + 4 = <<153+4=157>>157 cm.
