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

### Instruction:
Emily bought a shirt and a coat for $600. What does the shirt cost if it is one-third the price of the coat?

### Response:
 Acha X iwe bei ya shati.
Bei ya koti ni X*3.
Jumla ya kiasi ni X + X*3 = $<<600=600>>600.
Kwa kuunganisha vipengele sawa, tunapata X*4 = $600.
Kwa kugawanya pande zote mbili kwa 4, tunapata X = $600 / 4 = $<<600/4=150>>150.
