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

### Instruction:
A laboratory needs flasks, test tubes, and safety gear to carry out its experiments. They were given a $325 budget for the month. They bought $150 worth of flasks, spent two-thirds of that amount on test tubes, and used half of the test tube cost on safety gear. How many dollars of their budget remained?

### Response:
 Maabara ilikatia gharama ya $150 kwa vikombe vya kupimia, na theluthi mbili ya kiasi hicho kwa mifuko ya majaribio, ambayo ni $150*2/3 = <<150*2/3=100>>100.
Walitumia nusu ya gharama ya mifuko ya majaribio kwa vifaa vya usalama, ambayo ni $100/2 = <<100/2=50>>50.
Walitumia jumla ya $150 + $100 + $50 = <<150+100+50=300>>300.
Walibakiwa na $325 - $300 = <<325-300=25>>25 katika bajeti yao ya awali.
