Question: The first tank is 300 liters filled while the second tank is 450 liters filled. The second tank is only 45% filled. If the two tanks have the same capacity, how many more liters of water are needed to fill the two tanks?
Answer: Since 450 liters represents 45%, then each 1% is equal to 450 liters / 45 = 10 liters. Hence, the capacity of each tank is 10 liters x 100 = 1000 liters. So, the first tank needs 1000 - 300 = 700 liters of water more. While the second tank needs 1000 - 450 = 550 liters more. Therefore, 700 + 550 = 1250 liters of water are needed to fill the two tanks. The answer is 1250.
[Question]Jenny leaves her house at 8:00 with some cupcakes for her daughter's birthday party at school. She jogs to the school at 15 miles per hour. Half an hour later, her wife Anna realizes that Jenny used peanut butter frosting because she forgot one of the kids in the class had a severe peanut allergy. Jenny doesn't have her cell phone, so Anna leaves the house driving at 45 miles her hour to catch Jenny and warn her. How long does Anna spend traveling in minutes?
[Answer]We know that the time that Anna spends traveling is 20 minutes less than Jenny's travel time: a = j - 20. We also know that the distance both people travel is equal, so their speeds times their travel times must be equal: 15j = 45a. Substituting the first equation into the second equation, we get 15j = 45(j - 20). Multiplying through the parentheses we get 15 j = 45j - 900. Subtracting 45 j from both sides, we get - 30j = - 900. Dividing both sides by - 30, we get j = 30. Since Anna travels 20 minutes less than Jenny, she traveled 30 minutes - 20 minutes = 10 minutes. The answer is 10.
Q: Dexter filled 3 fewer plastic boxes with football cards than basketball cards. He filled 9 boxes with basketball cards and each box has 15 cards. For the boxes with football cards, he filled each box with 20 cards. How many cards does Dexter have in total?
A: Dexter have 9 x 15 = 135 basketball cards. He filled 9 - 3 = 6 plastic boxes with football cards. So, he has 6 x 20 = 120 football cards. Therefore, Dexter has 135 + 120 = 255 cards in total. The answer is 255.

[Question]Braden had $400 in his money box. He had also placed a bet today with Byan that the Raptors will beat the Bulls. If the game's outcome was as Braden predicted, and he and Bryan had agreed to give the winner twice as much money as Braden had in his money box, calculate the total amount of money Braden had in his money box after winning the bet?
[Answer]If they agreed to give the winner twice as much money as Braden had in his money box, after winning the bet, Braden received 2 * $400 = $800. Braden increased the total amount of money in his money box to $800 + $400 = $1200. The answer is 1200.
[Question]Janet has 9 cards more than Brenda. Mara has twice as many cards as Janet. How many cards do they have in all if Mara has 40 cards less than 150?
[Answer]
Mara has 150 - 40 = 110 cards. Janet has 110 / 2 = 55 cards since Mara has twice as many as Janet. Brenda has 55 - 9 = 46 cards since Janet has 9 cards more than Brenda. Therefore, they all have 110 + 55 + 46 = 211 cards. The answer is 211.
