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

### Instruction:
Miss Davis gave 15 popsicle sticks to each of the 10 groups in her class. How many sticks does she have left if she had 170 popsicle sticks?

### Response:
 Bi Davis alitoa jumla ya vijiti vya barafu 15 x 10 = <<15*10=150>>150 kwa makundi 10 katika darasa lake.
Hivyo, amebakiwa na vijiti 170 - 150 = <<170-150=20>>20.
