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

### Instruction:
 Penn anafanya biashara ya kuuza ice cream kwa wiki. Siku ya kwanza, alipata $10. Kila siku baada ya hapo, alipata $4 zaidi ya siku iliyopita. Penn alipata pesa kiasi gani baada ya siku 5?


### Response:
 Baada ya siku ya kwanza, Penn alipata $10 + $4 = $14 siku ya pili.
Siku ya tatu, alipata $14 + $4 = $18.
Siku ya nne, alipata $18 + $4 = $22.
Siku ya tano, alipata $22 + $4 = $26.
Baada ya siku 5, Penn alipata jumla ya $10 + $14 + $18 + $22 + $26 = $90.
