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

### Instruction:
A luxury perfume costs $1200. The store owner decided to increase its price by 10% so that he could earn more profit. Few weeks had past but the perfume was still not sold. So, the owner decided to lower the price by 15%. By how much was the final price lower than the original price?

### Response:
 Kwanza tafuta bei mpya baada ya ongezeko la 10%: 1200 * 1.1 = <<1200*1.1=1320>>1320
Kisha tafuta bei mpya baada ya kupungua kwa 15%: 1320 * 0.85 = <<1320*.85=1122>>1122
Hatimaye, toa tofauti kati ya bei ya mwisho na bei ya awali: 1200 - 1122 = <<1200-1122=78>>78
