[Question]Liam and Claire picked and sold oranges to save for their mother's birthday gift. Liam picked 40 oranges and sold them at $2.50 for 2 while Claire picked 30 oranges and sold them at $1.20 each. If all of their oranges were sold, how much are they going to save for their mother's birthday gift?
[Answer]Liam sold 40 / 2 = 20 sets of oranges that cost $2.50 for each set. So, Liam earned $2.50 x 20 = $50. Claire earned $1.20 x 30 = $36. Thus, they were able to save $50 + $36 = $86 for their mother's birthday gift. The answer is 86.
Q: As firefighters, Doug, Kai, and Eli have been putting out a lot of fires over the week. Doug has put out 20 fires for the week and Kai has put out 3 times more than Doug. Meanwhile, Eli has put out half the number of fires Kai was able to. How many fires have they put out for the entire week?
A: Kai has put out 20 x 3 = 60 fires for the week. Eli has put out 60 / 2 = 30 fires for the week. Therefore, the total amount of fires they have put out over the entire week was 20 + 60 + 30 = 110. The answer is 110.
Question: Liam wants to go to Paris, but first, he has to pay his bills. His trip costs $7,000, and his bills cost $3,500. Knowing that Liam has saved $500/month for 2 years, how much money will he have left after paying his bills?
Answer: In total Liam has saved ($500 / month * 12 months / year) * 2 years = $12,000. When Liam pays his bills, he will have $12,000 - $3,500 = $8,500 left. The answer is 8500.
[Question]Marty and Biff were both running for student council president. A poll was taken to see how the candidate’s campaigns were going. 45% of the people polled said they were voting for Biff and 8% were undecided. The rest said they are voting for Marty. If 200 people were polled, how many said they are voting for Marty?
[Answer]If 45% of people were voting for Biff + 8% were undecided = 53% were not voting for Marty. There were 100 – 53 = 47% voting for Marty. If 47% of 200 people were voting for Marty, 0.47 x 200 = 94 people said they were voting for Marty. The answer is 94.
Q: The bagels cost $2.25 each, or a dozen for $24. How much is saved, per bagel, in cents, by buying a dozen at a time?
A: They cost 2.25 * 100 = 225 cents each. At the bulk rate, they are 24 / 12 = 2 dollar each. They cost 2 * 100 = 200 cents each. 225 - 200 = 25 cents are saved per bagel. The answer is 25.
Question: Val has three times as many dimes as nickels. If she accidentally finds twice as many nickels as she has in her older brother's treasure box, and takes them for herself, what would be the value of money she has, in dollars, if she had 20 nickels before finding the new ones from her brother's treasure box?
Answer:
If Val currently has 20 nickels and finds twice as many nickels as she has in her older brother's treasure box, she will have 2 * 20 = 40 more nickels. The total number of nickels she'll have is 40 + 20 = 60. Since nickel is worth $0.05, the value of the nickels Val is having is 60 * 0.05 = $3. Val had three times as many dimes as nickels before she found the 40 new nickels, a total of 3 * 20 = 60 dimes. Since a dime has a value of $0.10, the value of the dimes that Val has is 60 * $0.10 = $6. Together, the value of the dimes and nickels Val has is worth $6 + $3 = $9. The answer is 9.
