Question: 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?
Answer: 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]A shady restaurant is charging customers gratuities after taxes without them being aware. If my total bill was $140, the sales tax in my city is 10%, I ordered a NY Striploin for $80, and I ordered a glass of wine for $10, how much did they charge me for gratuities?
[Answer]The total bill before taxes or gratuities was $80 for the steak + $10 for the wine = $80 + $10 = $90. If the tax is 10%, then the taxes paid were $90 * 10% = $9. That means that the total bill before gratuities was $90 + $9 = $99. If the final bill was $140, then you were charged $140 - $99 = $41 for gratuities. The answer is 41.

Question: Itzayana is 4 inches taller than Zora, who is 8 inches shorter than Brixton. If Zara is 64 inches tall and has the same height as Brixton, calculate the average height of the four people.
Answer: Since Brixton has the same height as Zara which is 64 inches, Zora, who is 8 inches shorter than Brixton, is 64 - 8 = 56 inches tall. Zara and Brixton's height is 64 + 64 = 128 inches. If you add Zora's height, the three have a total height of 128 + 56 = 184. Itzayana is 4 inches taller than Zoran which means she is 56 + 4 = 60 inches tall. The total height of the four friends is 60 + 184 = 244. The average height of the three is 244 / 4 = 61. The answer is 61.
[Question]Danielle bought a new house for $280k. She paid a $40k deposit on the house, and pays the rest using a mortgage that is spread out over 10 years. Danielle makes equal payments every month and at the end of the 10 years, the entire balance will be paid off. How much, in thousands of dollars, does Danielle pay each month?
[Answer]After paying the deposit, Danielle still has to pay a total of $280k purchase price - $40k deposit = $240k via her mortgage. As the mortgage is over 10 years, Danielle’s payments need to total $240k mortgage balance / 10 years = $24k per year. So each month, Danielle has to pay $24k per year / 12 months in a year = $2k per month. The answer is 2.
[Question]Gunner has a box of mittens with 20 fewer pairs than a box of plugs. He decides to put 30 more pairs of plugs into the box of plugs. If the box of mittens has 150 pairs of mittens, how many plugs are there?
[Answer]
Since there are 20 fewer mittens pairs than the plugs, there are 150 + 20 = 170 pairs of plugs. When Gunner decides to add 30 more plugs pairs into the box of plugs, the number of plug pairs increases to 170 + 30 = 200. Since a pair has two, the 200 pairs of plugs total 200 * 2 = 400 plugs. The answer is 400.
