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?
Let's think: 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.

Ken can do 20 sit-ups without stopping. Nathan can do twice as many, and Bob can do half the number of Ken and Nathan's combined sit-ups. How many more sit-ups can Bob do compared to Ken?
Let's think: Nathan can do 20 x 2 = 40 sit ups. Ken and Nathan's combined number is 20 + 40 = 60 sit - ups. Bob can do 60 / 2 = 30 sit - ups. Bob can do 30 - 20 = 10 more sit - ups than Ken.. The answer is: 10.

Nina makes one-of-a-kind jewelry and sells it at a local boutique. She charges $25.00 for her necklaces, $15.00 for bracelets and $10.00 for a pair of earrings. Over the weekend, she sold 5 necklaces, 10 bracelets, 20 earrings, and received 2 orders for a complete jewelry ensemble that Nina charged $45.00 for. How much money did she make over the weekend?
Let's think: She sold 5 necklaces at $25.00 apiece for a total of 5 * 25 = $125.00. She sold 10 bracelets for $15.00 each for a total of 10 * 15 = $150.00. She sold 20 earrings for $10.00 a pair for a total of 20 * 10 = $200.00. She sold 2 ensembles for $45.00 each for a total of 2 * 45 = $90.00. All total she made 125 + 150 + 200 + 90 = $565.00.. The answer is: 565.

Nico borrows 3 books from the library on Monday. On Monday, he reads the first book with a total of 20 pages. On Tuesday, he reads the second book with a total of 12 pages. On Wednesday, he reads the third book. If he has read a total of 51 pages from Monday to Wednesday, how many pages did he read on Wednesday?
Let's think:
From Monday to Tuesday, Nico reads a total of 20 + 12 = 32 pages. On Wednesday, he read a total of 51 - 32 = 19 pages.. The answer is: 19.
