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

### Instruction:
Lucy lost one-third of her money. She then spent one-fourth of the remainder, and only left with $15. How much money did Lucy have at the beginning?

### Response:
 Theluthi moja ya pesa ya Lucy ni 1 - 1/3 = 2/3.
Hivyo, Lucy ana 2/3 * $x = $x - $x/3 = $x - $x/3 = $x - $x/2 = $x/2 iliyosalia.
Robo moja ya pesa iliyosalia ni 1/4 * $x/2 = $x/8.
Hivyo, Lucy alitumia $x/8 na akabaki na $15, ambayo inamaanisha $x/8 + $15 = $x/2.
Hii inalingana na $x = 2 * 15 = $30.
