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

### Instruction:
Jenny is scraping gum off the bottom of the seats in a stadium with two sections. Section A has 1 subsection with 60 seats and 3 subsections with 80 seats each. Section B has 20 more seats than 3 times as many seats as Section A has total. How many seats does Section B have?

### Response:
 Kwanza tafuta idadi ya viti katika sehemu tatu zenye viti 80: 80 viti/sehemu * 3 sehemu = 240 viti
Kisha ongeza idadi ya viti katika sehemu yenye viti 60 ili kupata idadi ya jumla ya viti katika Sehemu A: 240 viti + 60 viti = 300 viti
Kisha mara tatu idadi hiyo: 300 viti * 3 = 900 viti
Kisha ongeza viti 20 ili kupata idadi ya jumla ya viti katika Sehemu B: 900 viti + 20 viti = 920 viti
