[Question]: 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?
[Answer]: 35 bones at the end - 10 received = 25 on Sunday. Lassie ate half, so multiply by two to find the number of bones at the beginning which is 25 * 2 = 50 bones.
So the answer is 50.

[Question]: Matt can buy key chains in packs of 10 for $20 or in packs of 4 for $12. How much money can he save if he chooses to buy 20 key chains at a lower price?
[Answer]: The cost of each key chain in packs of 10 for $20 is $20 / 10 = $2. The cost of each key chain in packs of 4 for $12 is $12 / 4 = $3. There is a price difference of $3 - $2 = $1 per key chain between the two choices. By buying 20 key chains at a lower price, Matt can save 20x$1 = $20.
So the answer is 20.

He picked 80 peppers because 7 + 12 + 14 + 12 + 5 + 18 + 12 = 80. 80% of the peppers are not hot because 100 - 20 = 80. He picked 64 non - hot peppers because 80 x .8 = 64.
So the answer is 64.
