Q: Dolly wants to ride the Ferris wheel twice, the roller coaster three times, and the log ride seven times. The Ferris wheel costs 2 tickets, the roller coaster costs 5 tickets and the log ride costs 1 ticket. Dolly has 20 tickets. How many more tickets should Dolly buy?
A: It costs 2 rides x 2 tickets / ride = 4 tickets to ride the Ferris wheel twice. It costs 3 rides x 5 tickets / ride = 15 tickets to ride the roller coaster three times. It costs 7 rides x 1 ticket / ride = 7 tickets to ride the roller coaster seven times. In total Dolly needs 4 tickets + 15 tickets + 7 tickets = 26 tickets. Dolly needs to buy 26 tickets - 20 tickets = 6 more tickets. The answer is 6.
Question: Every 4 weeks, Helen hand washes her silk pillowcases. It takes 30 minutes to hand wash all of them. In 1 year, how much time does Helen spend hand washing her pillowcases?
Answer: She hand washes them every 4 weeks and there are 52 weeks in a year so she washes them 52 / 4 = 13 times per year. It takes her 30 minutes to hand wash the pillowcases and she does this 13 times per year for a total of 30 * 13 = 390 minutes per year. The answer is 390.
[Question]Uncle Ben has 440 chickens on his farm. 39 are roosters and the rest are hens. 15 of his hens do not lay eggs, and the rest do. If each egg-laying hen lays 3 eggs, how many eggs will Uncle Ben have?
[Answer]Uncle Ben has 440 chickens - 39 roosters = 401 hens. Uncle Ben has 401 hens - 15 that don't lay eggs = 386 hens that lay eggs. The egg - laying hens each lay 3 eggs * 386 hens = 1158 eggs. The answer is 1158.
Q: Between them, Mark and Sarah have 24 traffic tickets. Mark has twice as many parking tickets as Sarah, and they each have an equal number of speeding tickets. If Sarah has 6 speeding tickets, how many parking tickets does Mark have?
A: First figure out how many total speeding tickets the two people got by adding the 6 speeding tickets Sarah got to the equal number (6) that Mark got: 6 + 6 = 12. Now subtract the combined number of speeding tickets from the total number of tickets to find the combined number of parking tickets: 24 - 12 = 12. Now express Mark's number of parking tickets in terms of the number of parking tickets Sarah got: m = 2s. We know that m + s = 12, so substitute in the value of m from the previous step to get 2s + s = 12. Combine like terms to get 3s = 12. Divide both sides of the equation to get s = 4. Now multiply the number of parking tickets Sarah got by 2 to find the number Mark got: 4 * 2 = 8. The answer is 8.
Question: Baseball season opened up with the Chicago Cubs at home at Wrigley Field. They scored 2 home runs in the third inning, 1 home run in the fifth inning and 2 more home runs in the eighth inning. Their opponents, the Cardinals, scored 1 home run in the second inning and 1 home run in the fifth inning. How many more home runs did the Chicago Cubs score than the Cardinals in the game?
Answer: The Chicago Cubs scored 2 home runs in the third inning, 1 home run in the fifth inning, and 2 home runs in the eighth for a combined total of 2 + 1 + 2 = 5 home runs for the game. The Cardinals scored 1 home run in the second inning and 1 home run in the fifth inning for a combined total of 1 + 1 = 2 home runs for the game. If the Chicago Cubs scored a total of 5 home runs in the game and the Cardinals scored a total of 2 home runs in the games then 5 - 2 = 3 more home runs were scored by the Chicago Cubs than the Cardinals in the game. The answer is 3.
Q: James takes up dancing for fitness. He loses twice as many calories per hour as he did when he was walking. He dances twice a day for .5 hours each time and he does this 4 times a week. He burned 300 calories an hour walking. How many calories does he lose a week from dancing?
A:
He burns 2 * 300 = 600 calories an hour. He dances for .5 * 2 = 1 hour per day. So he burns 600 * 1 = 600 calories per day. So he burns 600 * 4 = 2400 calories per week. The answer is 2400.
