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

### Instruction:
Erwan went on shopping. He purchased a pair of shoes at $200 but discounted 30%, and two shirts at $80 each. Upon checkout, the cashier said that there is an additional 5% discount. How much did he spend after all the discounts?

### Response:
 Punguzo jumla la jozi ya viatu ni $200 x 30/100 = $<<200*30/100=60>>60.
Aliulipa $200 - $60 = $<<200-60=140>>140 kwa jozi ya viatu.
Gharama jumla ya mashati mawili ni $80 x 2 = $<<80*2=160>>160.
Hivyo, Erwan alitumia $140 + $160 = $<<140+160=300>>300 kwa viatu na mashati mawili.
Alipata punguzo la ziada la $300 x 5/100 = $<<300*5/100=15>>15 wakati wa kulipa.
Hivyo, Erwan alitumia $300 - 15 = $<<300-15=285>>285 baada ya punguzo zote.
