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? Let's answer step by step:
User
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: 48.
