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

### Instruction:
Leah earned $28 working odd jobs around the neighborhood. She spent a seventh of it on a milkshake and put half of the rest in her savings account. She left the remaining money in her wallet. Her dog got ahold of her wallet and shredded all the money inside but $1. How many dollars did Leah lose?

### Response:
 Leah alitumia 28 / 7 = $<<28/7=4>>4 kununua milkshake.
Aliyobaki nayo ni 28 - 4 = $<<28-4=24>>24.
Aliweka nusu yake, au 24 / 2 = $<<24/2=12>>12, kwenye akaunti yake ya akiba.
Aliacha 24 - 12 = $<<24-12=12>>12 kwenye mkoba wake.
Mbwa wake alirarua pesa zote kwenye mkoba wake isipokuwa $1, hivyo Leah alipoteza 12 - 1 = $<<12-1=11>>11.
