Q: Ryan's party was 4 times as huge as Taylor's birthday party. If both parties combined had 240 people, how many people were there at Ryan's party?
A: To get the number of people at Taylor's party, we'll assume there were n people at his party. The total number of people at Ryan's party is 4 * n, four times the number of attendees at Taylor's party. Combined, there were 4n + n = 240 people at both parties. This translates to 5n = 240. The total number of people at Taylor's party is n = 240 / 5. There were n = 48 people at Taylor's party. Since Ryan's party was 4 times as huge as Taylor's party, at Ryan's party, there were 48 * 4 = 192 people. The answer is 192.
Question: Pete has to take a 10-minute walk down to the train station and then board a 1hr 20-minute train to LA. When should he leave if he cannot get to LA later than 0900 hours? (24-hr time)
Answer: There are 60 minutes in an hour so 1 hour 20 minutes = (60 + 20) minutes = 80 minutes. He will spend a total of 80 + 10 = 90 minutes. 90 minutes is = (60 / 60) hours and 30 minutes = 1 hour 30 minutes = 0130 in 24 - hr time. He has to leave 0130 hours earlier than 0900 i.e. 0900 - 0130 = 0730 hours. The answer is 730.
[Question]Melody planted sunflowers from two different seed packets. She found that the sunflowers from Packet A were 20% taller than the sunflowers from Packet B. If the sunflowers from Packet A were 192 inches tall, how tall were the sunflowers from Packet B?
[Answer]The height of the sunflowers from Packet A is the same as the height of the sunflowers from Packet B + 20%. If Y represents the height of the sunflowers from Packet B, Y + 0.20Y = the height of sunflowers from Packet A. We know the height of the sunflowers from Packet A is 192 inches = Y + 0.20Y or 1.2Y. To figure out Y, we would divide both sides of the equation by 1.2, like this: 192 / 1.2 = 1.2Y / 1.2 or 160 = Y. The answer is 160.
Q: Kevin holds the world record for eating the biggest quantity of hot wings in 8 minutes. He can eat 64 wings without stopping. Alan, a boy who loves hot wings, wants to beat Kevin's record. He is currently able to eat 5 hot wings per minute. How many more wings must he eat per minute to beat Kevin's record?
A: Knowing Kevin's record of eating 70 wings in 8 minutes or 64 / 8 = 8 wings in a minute. Alan must increase his ability to eat 5 wings per minute to 8 - 5 = 3 wings per minute to equal Kevin's world record. To beat Kevin, Alan must eat 3 + 1 = 4 hot wings per minute. The answer is 4.
Question: Karen has 32 quarters in her piggy bank. Her older brother Christopher has 64 quarters in his piggy bank. How much more money does Christopher have?
Answer:
Christopher has 64 quarters so he has 64 * .25 = $16.00. Karen has 32 quarters so she has 32 * .25 = $8.00. If Christopher has $16.00 and Karen has $8.00 then Christopher has 16 - 8 = $8.00 more than Karen. The answer is 8.
