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

### Instruction:
There's a sale at your favorite "Any item $10" retailer. If you buy 1 shirt you pay $10. If you buy 2, you get the second one at a 50% discount. If you buy 3, you get the third one at a 60% discount. How much money did you save if you bought 3 shirts?

### Response:
 Shati la kwanza halina punguzo (0%) kwenye bei ya kawaida ($10), kwa hivyo punguzo lako ni = 0% * $10 = $0.
Shati la pili lina punguzo la 50% kwenye bei ya kawaida ($10), kwa hivyo punguzo lako ni = 50% * $10 = $5.
Shati la tatu lina punguzo la 60% kwenye bei ya kawaida ($10), kwa hivyo punguzo lako ni = 60% * $10 = $6.
Kwa hivyo jumla ya punguzo lako kwa kununua mashati 3 ni = $0 + $5 + $6 = $11.
