### Instruction:
Lassie eats half of her bones on Saturday. On Sunday she received 10 more bones. She now has a total of 35 bones. How many bones did she start with before eating them on Saturday?

### Response:
 Mifupa 35 mwishoni - 10 iliyopokelewa = 25 Jumapili.
Lassie alila nusu, hivyo mnoa kwa mbili ili kupata idadi ya mifupa mwanzoni ambayo ni 25 * 2 = <<25*2=50>>50 mifupa.
