Q: A class of 30 high school students is preparing for a field trip. If each student contributes $2 every Friday for their trip, how many dollars will they have in 2 months?
A: They save 30 students * $2 / student / week = $60 / week. They saved for 2 months which is 2 months * 4 weeks / month = 8 weeks. So in 2 months, they will have $60 / week * 8 weeks = $480. The answer is 480.
Question: Tony, Moses and Esther are to share $50. Moses will take 40% of the total amount while Tony and Esther will split the remainder equally among themselves. How much more than Esther will Moses get?
Answer: 40% of $50 is (40 / 100) * $50 = $20. After Moses takes $20, there will be $50 - $20 = $30 left. Tony and Esther will split $30 equally among themselves so each of them will get $30 / 2 = $15. Moses gets $20 - $15 = $5 more than Esther. The answer is 5.
[Question]Carl is figuring out how much he'll need to spend on gas for his upcoming road trip to the Grand Canyon. His car gets 30 miles per gallon in cities and 40 miles per gallon on the highway. The distance from his house to the Grand Canyon, one way, is 60 city miles and 200 highway miles. If gas costs $3.00 per gallon, how much will Carl need to spend?
[Answer]First figure out how many city miles Carl will drive round trip by multiplying the one - way number of city miles by 2: 60 miles * 2 = 120 miles. Then figure out how many highway miles Carl will drive round trip by multiplying the one - way number of highway miles by 2: 200 miles * 2 = 400 miles. Now divide the round - trip number of city miles by the number of city miles per gallon Carl's car gets: 120 miles / 30 mpg = 4 gallons. Now divide the round - trip number of highway miles by the number of highway miles per gallon Carl's car gets: 400 miles / 40 mpg = 10 gallons. Now add the gallons for the highway miles and the city miles to find the total number of gallons Carl needs to buy: 10 gallons + 4 gallons = 14 gallons. Finally, multiply the number of gallons Carl needs to buy by the cost per gallon to find out how much he spends: 14 gallons * $3.00 = $42.00. The answer is 42.
Q: A jar full of marbles is sitting on a table. Half of the marbles are blue, a quarter of them are red, 27 of them are green, and 14 of them are yellow. How many marbles are in the jar?
A: Let x = the number of marbles in the jar. If 50% of the marbles are blue, and 25% of them are red, then the remaining 25% must be either green or yellow. So 0.25 * x = 27 green marbles + 14 yellow marbles = 41 marbles. So there are a total of 4 * 41 = 164 marbles in the jar. The answer is 164.
