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

### Instruction:
 Shule inaongeza safu 5 za viti kwenye ukumbi wa michezo. Kila safu ina viti 8 na kila kiti kina gharama ya $30. Mzazi, akiwa mtengenezaji wa viti, alitoa punguzo la 10% kwa kila kundi la viti 10 vinavyonunuliwa. Shule italipa kiasi gani kwa viti vipya?


### Response:
 Kuna viti 40 kwenye safu, na safu 5, kwa hivyo kuna viti 40/viti * 5 safu = <<40*5=200>>200 viti.
Ikiwa kila kiti kinagharimu $30, basi gharama jumla ni $30/kiti * 200 viti = <<30*200=6000>>6000 dola.
Mzazi anatoa punguzo la 10% kwa kila kundi la viti 10, kwa hivyo punguzo kwa viti 200 ni: $6000 * 10% = <<6000*.1=600>>600 dola.
Hatimaye, gharama jumla ni $6000 - $600 = $<<6000-600=5400>>5400 dola.
