Question: Cara has 60 marbles in a bag. 20 of them are yellow, half as many are green, and the remaining marbles are equally divided between red and blue. If Cara picks a marble at random, what are the odds it's blue (expressed as a percentage)?
Answer: First find the number of green marbles: 20 yellow marbles / 2 = 10 green marbles. Then find how many marbles are either red or blue: 60 marbles - 20 yellow marbles - 10 green marbles = 30 marbles. Divide this number in half to find how many marbles are blue: 30 marbles / 2 = 15 blue marbles. Finally, divide the number of blue marbles by the total number of marbles and multiply by 100 to find the percentage chance of getting a blue marble: 15 marbles / 60 marbles * 100 = 25%. The answer is 25.
[Question]Jeremy is driving 600 miles to visit his parents. His average speed for this trip is 50 miles per hour. Every two hours of driving, he makes a rest stop for 15 minutes. His car gets 18 miles per gallon of gas, and his gas indicator comes on when he's used 15 gallons, at which point he stops to refill, which takes 10 minutes. How long, in minutes, does he take to get to his parents' house, if he starts out with a full tank of gas?
[Answer]Jeremy is driving 600 miles, at an average speed of 50 miles per hour, so he will be driving for 600 miles / 50 miles per hour = 12 hours * 60 minutes per hour = 720 minutes. He makes a rest stop every 2 hours of driving, at 2, 4, 6, 8 & 10 hours in = 5 rest stops on the trips. Each rest stop takes 15 minutes so he will spend 5 rest stops * 15 minutes per rest stop = 75 minutes on rest stops. His car gets 18 miles to the gallon, and he stops to refill every 15 gallons, so he will stop to refill every 18 miles per gallon * 15 gallons = 270 miles. 600 miles / 270 miles per refuel = 2.22 refuels, so he'll only make 2 refuels during the trip. He will spend 2 refuels * 10 minute per refuel = 20 minutes refueling his car. In total he will take 720 minutes driving + 75 minutes resting + 20 minutes refueling = 815 minutes. The answer is 815.
Q: Amanda's car takes five fewer minutes to complete the same trip to the beach than the bus. If the bus takes 40 minutes to drive 80 miles to the beach, how many minutes will it take the car to make a round trip?
A: If the bus takes 40 minutes to complete 80 miles of a trip, Amanda's car, which takes five fewer minutes to complete a trip than the bus, will take 40 - 5 = 35 minutes to complete the trip. A round trip will take the car twice the time for going one way, a total of 35 + 35 = 70. The answer is 70.
Question: Melony makes $21 of profit every time she sells 3 shirts and four times as much profit when she sells two pairs of sandals. How much profit will she make if she sells 7 shirts and 3 pairs of sandals?
Answer: Melony makes $21 * 4 = $84 of profit for two pairs of sandals. Melony makes $84 / 2 pairs = $42 of profit per pair of shoes. Melony makes $21 / 3 shirts = $7 of profit per shirt. For seven shirts, Melony will make 7 shirts * $7 = $49 of profit. For three pairs of sandals, Melony will make 3 pairs * $42 / pair = $126 of profit. Melony will make a total of $49 + $126 = $175 of profit. The answer is 175.
[Question]Ray always takes the same route when he walks his dog. First, he walks 4 blocks to the park. Then he walks 7 blocks to the high school. Finally, he walks 11 blocks to get back home. Ray walks his dog 3 times each day. How many blocks does Ray's dog walk each day?
[Answer]The number of blocks in each walk around the neighborhood is 4 blocks + 7 blocks + 11 blocks = 22. Ray's dog walks 3 walks × 22 blocks / walk = 66 blocks each day. The answer is 66.
[Question]Lori owns a carsharing company. There are three red cars and two white cars available to rent. Renting the white car costs $2 for every minute and the red car $3 for every minute. All cars were rented for 3 hours. How much money did Lori earn?
[Answer]
Both white cars were rented for 2 * 2 = $4 for every minute. All three red cars were rented for 3 * 3 = $9 for every minute. So all Lori's cars were rented for 4 + 9 = $13 for every minute. Three hours are 180 minutes, so Lori earned 13 * 180 = $2340 for renting all the cars. The answer is 2340.
