[Question]Mary has 300 sheep and Bob has double the number of sheep as Mary plus another 35. How many sheep must Mary buy to have 69 fewer sheep than Bob?
[Answer]Bob has (300 * 2) + 35 = 635 sheep. For Mary to have 69 sheep fewer than Bob she must own 635 69 = 566 sheep. As Mary has already 300 sheep she must buy 566 300 = 266 sheep. The answer is 266.
Q: Malcolm is trying to find the fastest walk to school and is currently comparing two routes. In the first route, he walks for 6 minutes uphill, walks for twice this amount of time along a path, then finishes the journey in a third of the time it took to walk the first two stages. In the second route, he walks along a flat path for 14 minutes, then finishes the walk in twice this amount of time. In minutes, how much longer was the second route compared with the first?
A: In the first route, Malcolm spends 6 minutes * 2 = 12 minutes walking along the path. So in total, the first two stages of this route take him 6 + 12 = 18 minutes. This means the final part of the journey took him 18 / 3 = 6 minutes. Therefore, the total time it takes to walk the first route is 18 + 6 = 24 minutes. In the second route, the second stage takes him 14 * 2 = 28 minutes. So the second route takes a total of 28 + 14 = 42 minutes to walk. The second route therefore takes an extra 42 minutes for the second route 24 minutes for the first route = 18 minutes. The answer is 18.
Question: A pharmacy is buying enough tubs for them to make their prescriptions this week. They already have 20 tubs left in storage but they need a total of 100 tubs for the week. Of the tubs they still need to buy, they buy a quarter from a new vendor then decide to go to their usual vendor for the rest. How many tubs is the pharmacy going to buy from the usual vendor?
Answer: They already have 20 tubs in storage, so they only need to buy 100 needed tubs - 20 tubs in storage = 80 tubs. From the new vendor, they buy 80 tubs / 4 = 20 tubs. They now have a total of 20 + 20 = 40 tubs. They are therefore going to buy 100 needed tubs - 40 owned tubs = 60 tubs from the usual vendor. The answer is 60.
[Question]Three train stations are 2 hours apart from one another. Kira travels from the first station to the third, taking a 30 minutes break at the second station. What's the total time, in minutes, that Kira takes to travel between the first and third station?
[Answer]Travel between the three stations takes 2 + 2 = 4 hours. The total time for the journey is 4 * 60 = 240 minutes. If Kira takes a 30 - minute break, her journey takes 240 + 30 = 270 minutes. The answer is 270.
Q: There are 70 cookies in a jar. If there are only 28 cookies left after a week, and Paul took out the same amount each day, how many cookies did he take out in four days?
A: Paul took out a total of 70 - 28 = 42 cookies in a week. Paul took out 42 / 7 = 6 cookies out of the jar each day. Over four days, Paul took out 6 * 4 = 24 cookies from the jar. The answer is 24.
Question: Emma got $2000 from the bank. She bought $400 of furniture and gave 3/4 of the rest to her friend Anna. How much is left with Emma?
Answer:
Emma had $2000 - $400 = $1600 left after buying furniture. Emma gave Anna 3 / 4 * $1600 = $1200. So, Emma is left with $1600 - $1200 = $400. The answer is 400.
