Reasoning and answer: Marco gets 28 / 1 / 5 = 28 * 5 = 140 cups of tea from a box. At 7 days a week, Marco gets 140 / 7 = 20 weeks of daily tea from a box.
The answer: 20

Question: Marco uses a fifth of an ounce of dry tea leaves to brew his morning cup of tea each day. He buys tea leaves in boxes of 28 ounces. How many weeks of daily tea does Marco get from a box?


First figure out how many total speeding tickets the two people got by adding the 6 speeding tickets Sarah got to the equal number (6) that Mark got: 6 + 6 = 12. Now subtract the combined number of speeding tickets from the total number of tickets to find the combined number of parking tickets: 24 - 12 = 12. Now express Mark's number of parking tickets in terms of the number of parking tickets Sarah got: m = 2s. We know that m + s = 12, so substitute in the value of m from the previous step to get 2s + s = 12. Combine like terms to get 3s = 12. Divide both sides of the equation to get s = 4. Now multiply the number of parking tickets Sarah got by 2 to find the number Mark got: 4 * 2 = 8.
The answer: 8
Reverse engineering the question: Between them, Mark and Sarah have 24 traffic tickets. Mark has twice as many parking tickets as Sarah, and they each have an equal number of speeding tickets. If Sarah has 6 speeding tickets, how many parking tickets does Mark have?

Emmy has 14 - 6 = 8 iPods left. Rosa has 8 / 2 = 4 iPods. Emmy and Rosa have 8 + 4 = 12 iPods together.
The answer: 12
Reverse engineering the question: Emmy has a collection of 14 iPods. She loses 6 out of the 14 she had but she still has twice as many as Rosa. How many iPods does Emmy and Rosa have together?


Reasoning and answer: The money he earned from an oil change is $20 x 5 = $ 100. The money he earned from the repair is $30 x 10 = $300. The money he earned from the car wash is $15 x 5 = $75. Therefore, Cid earned a total of $100 + $300 + $75 = $475.
The answer: 475

Reasoning and answer: In the first verse, 30 / 2 = 15 singers sang. In the second verse, 15 / 3 = 5 singers joined in. In the final verse, 30 - 15 - 5 = 10 singers joined for the whole choir to sing together.
The answer: 10
