Answer the following question.
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?
Step-by-step reasoning process: 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.

Answer the following question.
A train leaves its departure station with 6 coal cars, 12 iron cars, and 2 wood cars. Between each station, there are 6 miles, and it takes 25 minutes to travel between them. At each station, the train can deposit up to 2 coal cars, 3 iron cars, and 1 wood car. How many minutes will it take to deliver all the cars?
Step-by-step reasoning process: To deliver all the coal, you need to pass by 6 coal / 2 coal / station = 3 stations. To deliver all the iron, you need to pass by 12 iron / 3 iron / station = 4 stations. To deliver all the wood, you need to pass by 2 wood / 1 wood / station = 2 stations. So 4 stations are needed to deliver everything, so 4 stations * 25 minutes / station = 100 minutes are needed.
The answer is 100.

Answer the following question.
Thomas wants to throw a party for his best friend Casey. He needs to order enough chairs for all the party guests to sit in, one for each guest. First he orders 3 dozen chairs for 3 dozen guests he invites. Then he finds out that 1/3 of the guests want to bring a guest of their own, so Thomas needs to order more chairs. Eventually, Thomas finds out that 5 of the guests he originally invited can't make it. Thomas would also like to order 12 extra chairs just in case they need them. How many chairs is Thomas going to order for Casey's party?
Step-by-step reasoning process: Thomas originally orders chairs for 3 dozen guests, 12 x 3 = 36 guests. Thomas finds out that 1 / 3 of the guests want to bring a guest of their own, 1 / 3 of 36 = 12. The 12 guests bring a guest of their own each, 36 guests + 12 guests = 48. Thomas finds out that 20 of the guests can't make it, 48 guests - 5 guests = 43. Thomas wants to order an extra 12 chairs, 43 + 12 = 55. Thomas will need 55 chairs for the party.
The answer is 55.

Answer the following question.
Marie has 4 notebooks with 20 stamps each. She also has two binders with 50 stamps each. If she decides to only keep 1/4 of the stamps, how many stamps can she give away?
Step-by-step reasoning process: Marie has 4 x 20 = 80 stamps from her notebooks. And she has 2 x 50 = 100 stamps from her binders. So she has a total of 80 + 100 = 180 stamps. Marie decided to keep 180 x 1 / 4 = 45 stamps only. Therefore, she can give away 180 - 45 = 135 stamps.
The answer is 135.
