Question: Elsa started the day with 40 marbles. At breakfast, she lost 3 marbles while playing. At lunchtime, she gave her best friend Susie 5 marbles. In the afternoon, Elsa's mom bought her a new bag with 12 marbles. Susie came back and gave Elsa twice as many marbles as she received at lunch. How many marbles did Elsa end the day with?
Answer: Elsa had 40 marbles - 3 - 5 = 32 marbles. Elsa then gained 12 marbles + 32 = 44 marbles. At dinner Elsa received 2 * 5 marbles from Susie = 10 marbles. In total Elsa had 44 marbles + 10 = 54 marbles. The answer is 54.
[Question]Milton has some books about zoology and 4 times as many books about botany. If he has 80 books total, how many zoology books does he have?
[Answer]Let z be the number of zoology books and b be the number of botany books. We know that z + b = 80 and b = 4z. Substituting the second equation into the first equation, we get z + 4z = 80. Combining like terms, we get 5z = 80. Dividing both sides by 5, we get z = 16. The answer is 16.
Q: Jina likes to collect mascots. She has 5 teddies, 3 times more bunnies, and a koala bear. Her mom decided to give her two additional teddies for every bunny she has. How many mascots Jina has in total?
A: In the beginning, Jina has 5 teddies * 3 bunnies / teddy = 15 bunnies. So her mom decided to give her 15 bunnies * 2 teddies / bunny = 30 teddies. So in total Jina has 5 teddies + 15 bunnies + 1 koala + 30 teddies = 51 mascots. The answer is 51.
Question: Homer scored 400 points on the first try in a Candy crush game, 70 points fewer on the second try, and twice the number of points she scored on the second try on the third try. What's the total number of points that she scored in all tries?
Answer: If Homer scored 400 points on the first try, he scored 400 - 70 = 330 points on the second try. The total number of points that Homer scored in the game after two tries are 400 + 330 = 730. On the third try of the Candy crush game, Homer scored twice the number of points she scored on the second try, a total of 2 * 330 = 660 points. In all the tries of the game, Homer scored 660 + 730 = 1390 points. The answer is 1390.

[Question]Danai is decorating her house for Halloween. She puts 12 plastic skulls all around the house. She has 4 broomsticks, 1 for each side of the front and back doors to the house. She puts up 12 spiderwebs around various areas of the house. Danai puts twice as many pumpkins around the house as she put spiderwebs. She also places a large cauldron on the dining room table. If Danai has the budget left to buy 20 more decorations and has 10 left to put up, how many decorations will she put up in all?
[Answer]
Danai places 12 skulls + 4 broomsticks + 12 spiderwebs + 1 cauldron = 29 decorations. She also puts up twice as many pumpkins around the house as she put spiderwebs, 12 x 2 = 24 pumpkins. Danai will also add 20 + 10 decorations to the 29 + 24 decorations already up = 83 total decorations Danai will put up. The answer is 83.
