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

### Instruction:
Ralph has $54.00 worth of products in his cart.  At the register, he asks if he could have a 20% discount on an item with a small issue.  This item is $20.00 to start.  They agree.   Ralph also has a 10% coupon on his purchase, which he uses after the 20% discount on the item with the small issue.  How much will all of his items cost?

### Response:
 Anapata punguzo la 20% kwenye bidhaa ya $20.00, hivyo ni punguzo la $4.00.
Bidhaa hiyo ilikuwa na punguzo la $4.00, hivyo bei yake mpya ni $20.00 - $4.00 = $16.00.
Ana kuponu ya 10% kwenye ununuzi wake wa $54.00, hivyo ni punguzo la $5.40.
Anapata $5.40 kutoka kwenye kuponu ya 10% na $4.00 kutoka kwenye punguzo la 20%, hivyo ununuzi wake wa $54.00 sasa utagharimu $54.00 - $5.40 - $4.00 = $45.00.
