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

### Instruction:
Bella, Monica, and Rachel are friends who like jewelry. Bella has 10 earrings, which is 25% of Monica's earrings, and Monica has twice as many earrings as Rachel. How many earrings do all of the friends have?

### Response:
 Kwa kuwa Bella ana 100% / 25% = 4 mara chache vipuli kuliko Monica, hii inamaanisha kuwa Monica ana vipuli 10 * 4 = <<10*4=40>>40.
Rachel ana vipuli mara mbili chache kuliko Monica, ambayo inamaanisha ana vipuli 40 / 2 = <<40/2=20>>20.
Hivyo marafiki hawa watatu wana vipuli 20 + 40 + 10 = <<20+40+10=70>>70 jumla.
