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

### Instruction:
 Angus ana thamani ya alama za $20 chini ya Elsa. Ikiwa Elsa ana alama 60 na kila alama ina thamani ya $4, Angus ana alama ngapi?


### Response:
 Ikiwa kila alama ina thamani ya $4, basi thamani ya alama za $20 ni $20/$4 = <<20/4=5>>5 alama.
Angus ana alama 5 chini ya Elsa ambaye ana alama 60, hivyo Angus ana alama 60-5 = <<60-5=55>>55.
