[Question]Joe goes camping with his dad on a Friday. Joe's dad has 21 marshmallows, and Joe has four times as much marshmallows as his dad. If Joe’s dad roasts a third of his marshmallows, and Joe roasts half of his marshmallows, how many marshmallows did they roast in total?
[Answer]Joe’s dad roasts 21 / 3 = 7 of his marshmallows. Joe has 21 * 4 = 84 marshmallows. Joe roasts 84 / 2 = 42 of his marshmallows. Joe and his dad roasted 7 + 42 = 49 marshmallows in total. The answer is 49.
Q: Haley is getting ready to watch a comet fly over her house. She spends two hours shopping for a telescope, half an hour getting everything set up in the backyard, three times the setup time making snacks, and 20 minutes watching the comet. What percentage of the total time she spent on all those activities was spent watching the comet, rounded to the nearest percent?
A: First convert Haley's shopping time to minutes: 2 hours * 60 minutes / hour = 120 minutes. Then convert Haley's setup time to minutes: .5 hours * 60 minutes / hour = 30 minutes. Then find the total time she spends making a snack: 3 * 30 minutes = 90 minutes. Then add the time she spends on each activity to find the total time: 120 minutes + 30 minutes + 90 minutes = 240 minutes. Then divide the time she spends watching the comet by the total time and multiply by 100% to express the answer as a percentage: 20 minutes / 240 minutes = 8.333...%, which rounds down to 8%. The answer is 8.
Question: A year ago, the total cost of buying a lawnmower was 2/5 times less than the cost it goes for now. If the cost was $1800 a year ago, calculate how much it would cost Mr. Lucian to buy 4 such lawnmowers.
Answer: If the price of a lawnmower was $1800 a year ago, 2 / 5 less than the cost right now, then it now costs 2 / 5 * 1800 = $720 more to buy one lawnmower. The total cost of buying one lawnmower right now is $1800 + $720 = $2520. To purchase 4 such lawnmowers, Mr. Lucian will have to pay $2520 * 4 = $10080. The answer is 10080.
[Question]A farmer gets 20 pounds of bacon on average from a pig. He sells each pound for $6 at the monthly farmer’s market. This month’s pig is a runt that grew to only half the size of the average pig. How many dollars will the farmer make from the pig’s bacon?
[Answer]The pig grew to half the size of the average pig, so it will produce 20 / 2 = 10 pounds of bacon. The rancher will make 10 * 6 = $60 from the pig’s bacon. The answer is 60.
Q: John's car needs a new engine. The labor costs $75 an hour for 16 hours. The part itself cost $1200. How much did the repairs cost in total?

Question: Missy has an obedient dog and a stubborn dog. She has to yell at the stubborn dog four times for every one time she yells at the obedient dog. If she yells at the obedient dog 12 times, how many times does she yell at both dogs combined?
Answer:
First find the number of times Missy yells at the stubborn dog: 4 * 12 times = 48 times. Then add the number of times she yells at the obedient dog to find the total number of times she yells: 48 times + 12 times = 60 times. The answer is 60.
