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

### Instruction:
Penn operates an ice cream stall for a week. On the first day, she made $10. Every day after that, she made $4 more than the previous day. How much money did Penn make after 5 days?

### 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.
