Q: Every Halloween one house in the neighborhood gives out toothbrushes instead of candy, so it always gets egged and covered in toilet paper. If the owner spends 15 seconds cleaning up each egg and 30 minutes cleaning up each roll of toilet paper, how long (in minutes) will they have to spend cleaning up 60 eggs and 7 rolls of toilet paper?
A: First find how many eggs per minute the owner can clean up: 60 seconds / minute / 15 seconds / egg = 4 eggs / minute. Then divide the total number of eggs by the number of eggs cleaned per minute to find how long the owner spends cleaning them up: 60 eggs / 4 eggs / minute = 15 minutes. Then find the total time the owner spends cleaning up toilet paper: 7 rolls * 30 minutes / roll = 210 minutes. Finally, add that amount to the egg cleaning time to find the total cleaning time: 210 minutes + 15 minutes = 225 minutes. The answer is 225.
Question: The novelty shop on the Starship Conundrum sells magazines and chocolates. The cost of four chocolate bars is equal to the cost of 8 magazines. If one magazine costs $1, how much does a dozen chocolate bars cost, in dollars?
Answer: If one magazine costs $1, then 8 magazines cost 8 * $1 = $8. Let's define "x" as the cost of one chocolate bar. The cost of four chocolate bars is equal to the cost of 8 magazines and 4 * x = $8. Dividing each side by 4, we get the cost of one chocolate bar x = $2. Therefore, a dozen chocolate bars would cost 12 * $2 = $24. The answer is 24.
[Question]Thomas started saving for a car almost 2 years ago. For the first year, his weekly allowance was $50. In the second year, he got a job that pays $9 an hour at a coffee shop and worked 30 hours a week, so his parents discontinued his allowance. If the car he wants to buy is $15,000 and he spends $35 a week on himself, how much more money does Thomas need to buy the car by the end of the 2 years?
[Answer]There are 52 weeks in a year. For the first year, Thomas received 52 x 50 = $2600. In the second year, Thomas earned 9 x 30 = $270 a week. In a year, Thomas earned 52 x 270 = $14,040. The total for the two years is 14040 + 2600 = 16640. In 2 years, Thomas' weekly expenses amounted to $35 x (52 x 2) = $35 x 104 = $3640. By the end of 2 years, Thomas would have saved $16640 - $3640 = 13000. Thomas still needs $15,000 - 13000 = $2000. The answer is 2000.
Q: Eric has 4 ninja throwing stars. His friend Chad has twice as many. Then Jeff bought 2 ninja stars from Chad. Jeff now has 6 throwing stars. How many ninja throwing stars do they have altogether?
A: We know Eric has 4 stars and Chad has twice that amount, so Chad has 4 x 2 = 8 stars. Then Chad sells 2 of them to Jeff, so Chad has 8 2 = 6 stars. Altogether, Eric has 4 + Chad has 6 + Jeff has 6 = 16 stars. The answer is 16.
Question: Gretchen read that you should spend 10 minutes walking for every 90 minutes you spend sitting. If Gretchen spends 6 hours working at her desk, how long will she spend walking?
Answer: First find the total number of minutes Gretchen spends sitting at her desk: 6 hours * 60 minutes / hour = 360 minutes. Then divide this amount by 90 minutes to find how many walking breaks Gretchen takes: 360 minutes / 90 minutes / break = 4 breaks. Then multiply the number of breaks by the length of each break to find how long Gretchen spends walking: 4 breaks * 10 minutes / break = 40 minutes. The answer is 40.
Q: David swims the 100-meter freestyle in 48 seconds. He swims the 100-meter backstroke 4 seconds slower than he swims the 100-meter freestyle, he swims the 100-meter butterfly 3 seconds slower than he swims the 100-meter backstroke, and he swims the 100-meter breaststroke 2 seconds slower than he swims the 100-meter butterfly. What is the combined length of time, in seconds, it would take for him to swim all four 100-meter events (the freestyle, the backstroke, the butterfly, and the breaststroke)?
A:
David swims the 100m backstroke at 48 + 4 = 52 seconds. He swims the 100m butterfly at 52 + 3 = 55 seconds. He swims the 100m breaststroke at 55 + 2 = 57 seconds. IN total, it would take David 48 + 52 + 55 + 57 = 212 seconds. The answer is 212.
