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

### Instruction:
At a birthday party, there are 20 red balloons and 15 green balloons. Before the party started, 3 red and 2 green balloons burst. How many balloons are left?

### Response:
 Kuna jumla ya maballoni 20 + 15 = <<20+15=35>>35 kwenye sherehe.
Kati ya hayo, maballoni 3 + 2 = 5 yalipasuka.
Hivyo, kuna maballoni 35 - 5 = <<35-5=30>>30 yaliyosalia.
