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

### Instruction:
Eliza buys 200 ornamental rings to sell in their local shop, twice the number of the remaining stock. After selling 3/4 of the total stock, her mother buys 300 more ornamental rings, and after three days, sells 150. What's the total number of ornamental rings remaining in the store?

### Response:
 Ikiwa Eliza alinunua mara mbili idadi ya awali ya pete za mapambo, idadi ilikuwa 200/2 = <<200/2=100>>100 pete.
Jumla ya pete za mapambo zilizosalia dukani sasa ni 200 + 100 = <<200+100=300>>300 pete.
Anapouza 3/4 ya hisa, idadi ya pete zilizouzwa ni 3/4 * 300 = <<3/4*300=225>>225 pete.
Hisa iliyosalia ni 300 - 225 = <<300-225=75>>75 pete.
Mama yake anapoinunua pete 300 zaidi, hisa inaongezeka hadi 75 + 300 = <<75+300=375>>375 pete.
Kisha anauza 150, hivyo hisa inakuwa 375 - 150 = <<375-150=225>>225 pete.
