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

### Instruction:
The price of an iPhone fell 10% in a particular month and another 20% in the second month.  If the initial price was $1000, calculate the price after the second month.

### Response:
 Katika mwezi wa kwanza, bei ya iPhone ilishuka kwa 10/100*$1000 = $<<10/100*1000=100>>100
Bei mpya baada ya mwezi wa kwanza ni $1000-$100 = $<<1000-100=900>>900
Katika mwezi wa pili, bei ilishuka kwa 20% zaidi kwa 20/100*$900 = $<<20/100*900=180>>180
Bei mpya baada ya mwezi wa pili ni $900-$180 = $<<900-180=720>>720
