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

### Instruction:
Becky has 50 necklaces in her jewelry collection. 3 of the necklaces have broken beads so she collects the unbroken beads for crafting and throws the other parts of the 3 the necklaces out. Becky buys 5 new necklaces that week. She decides to give 15 of her old necklaces to her friends as gifts. How many necklaces does she own now?

### Response:
 Becky anaanza na mikufu 50 kisha anatupa 3, 50 - 3 = <<50-3=47>>47 mikufu.
Becky ananunua mikufu 5 mpya wiki hiyo, 47 + 5 = <<47+5=52>>52 mikufu.
Anatoa mikufu 17 kama zawadi kwa marafiki zake, 52 - 15 = <<37=37>>37 mikufu Becky anamiliki sasa.
