Every day Janet spends 8 minutes looking for her keys and another 3 minutes complaining after she finds them. If Janet stops losing her keys, how many minutes will she save every week? Give the rationale and then the answer.
Let's think step by step. First find the total time Janet spends looking for her key and complaining each day: 8 minutes / day + 3 minutes / day = 11 minutes / day. Then multiply that number by the number of days in a week to find the weekly time spent: 11 minutes / day * 7 days / week = 77 minutes.. The answer is: 77.

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? Give the rationale and then the answer.
Let's think step by step. 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.

Christian is twice as old as Brian. In eight more years, Brian will be 40 years old. How old will Christian be in eight years? Give the rationale and then the answer.
Let's think step by step. If in eight years Brian will be 40 years old, he is currently 40 - 8 = 32 years old. Since Christian is twice as old as Brian, he is 2 * 32 = 64 years old. In 8 years, Christian will be 64 + 8 = 72 years old.. The answer is: 72.
