Q: Natalie bought some food for a party she is organizing. She bought two cheesecakes, an apple pie, and a six-pack of muffins. The six-pack of muffins was two times more expensive than the cheesecake, and one cheesecake was only 25% cheaper than the apple pie. If the apple pie cost $12, how much did Natalie pay for all her shopping?
A: One cheesecake was 30% cheaper than the apple pie, which means, it was 25 / 100 * 12 = $3 cheaper. So for one cheesecake, Natalie needed to pay 12 - 3 = $9. The six - pack of muffins was two times more expensive than the cheesecake, which means its price was 9 * 2 = $18. So for two cheesecakes, Natalie paid also 9 * 2 = $18. So for all her shopping she paid 18 + 18 + 12 = $48. The answer is 48.

Q: If 3 crows eat 30 worms in one hour, how many worms will 5 crows eat in 2 hours?
A: If 3 crows eat 30 worms in one hour, then each crow eats 30 / 3 = 10 worms per hour. 5 crows will eat 5 * 10 = 50 worms per hour. Over two hours, 5 crows will eat 2 * 50 = 100 worms. The answer is 100.

Q: Victoria had $500. She went to the market and bought 2 packets of rice each at $20, 3 packets of wheat flour each at $25, and 1 soda at $150. What was her remaining balance?
A:
In total, she spent 2 * $20 + 3 * $25 + $150 = $265. Thus her remaining balance is $500 - $265 = $235. The answer is 235.
