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

### Instruction:
 Duka la zamani la Stella linao vitu 3 vya kuchezea, saa 2 na glasi 5 za kuuza. Anauza vichezeo kwa $5 kila kimoja. Saa zinauzwa kwa $15 kila moja. Glasi zinauzwa kwa $4 kila moja. Ikiwa alitumia $40 kununua vitu vyote na anauza bidhaa zake zote, atapata faida kiasi gani?


### Response:
 Vichezeo vitauzwa kwa 3 * $5 = $<<3*5=15>>15.
Saa zitamletea $15 * 2 = $<<15*2=30>>30.
Glasi zitauzwa kwa $4 * 5 = $<<4*5=20>>20.
Jumla, atapata $15 + $30 + $20 = $<<15+30+20=65>>65
Faida yake jumla itakuwa $65 - $40 = $<<65-40=25>>25.
