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

### Instruction:
George was selling some of his old toys on the internet. He managed to sell 3 little cars and a set of Legos. In total, he earned $45. How much did the Legos set cost, if one little car was sold for $5?

### Response:
 George aliuza magari 3, hivyo alipata magari 3 * $5/gari = $<<3*5=15>>15 kutoka kwao.
Gharama ya seti ya Legos ilikuwa $45 - $15 = $30.
