Q: Leila spent 3/4 of her savings on make-up and the rest on a sweater. If the sweater cost her $20, what were her original savings?
A: If Leila spent 3 / 4 of her savings on make - up, this means she spent 1 - 3 / 4 = 1 / 4 of her savings on a sweater. Let S be her original savings. If the sweater cost $20, this means 1 / 4 * S = $20. Thus S = $20 * 4 = $80. The answer is 80.
Question: Christine and Janice are having a contest to see who can throw a ball the highest. They each get three throws. On her first throw, Christine throws it 20 feet high. Janice's throw is 4 feet lower than Christine's. On their second throw, Christine throws it ten feet higher than her first throw and Janice throws it twice as high as her first throw. On the final throw, Christine throws it 4 feet higher than her 2nd throw while Janice throws it 17 feet higher than Christine's first throw. What is the height of the highest throw?
Answer: We know Christine's second throw was 30 feet high because 20 + 10 = 30. We know Christine's third throw was 34 feet because 30 + 4 = 34. Janice's first throw was 16 feet because 20 - 4 = 16. Janice's second throw was 32 feet because 16 * 2 = 32. Janice's final throw was 37 feet high because 20 + 17 = 37. The six throws were 20 feet, 30 feet, 34 feet, 16 feet, 32 feet, and 37 feet, and of these numbers, 37 feet was the highest. The answer is 37.
[Question]Three friends went out to watch a movie. Mitch paid for their tickets at $7 each. On the other hand, Jam paid for the 2 boxes of popcorn at $1.5 while Jay paid for the 3 cups of milk tea at $3 each. If the three of them will split the total expenses, how much should each contribute?
[Answer]Three tickets cost $7 x 3 = $21. Two boxes of popcorn cost $1.5 x 2 = $3. Three cups of milk tea cost $3 x 3 = $9. The total expenses for the their tickets and food are $21 + $3 + $9 = $33. So, each of them should contribute $33 / 3 = $11. The answer is 11.

Question: Andy had a platter of chocolate cookies. He ate 3 of them then gave his little brother 5 because he was behaving. He then handed the platter to his basketball team of eight members. The first player to arrive took 1, the second player to arrive took 3, the third player took 5, and so on. When the last player took his share, the platter was empty. How many chocolate cookies did Andy have from start with?
Answer: Andy and his brother ate 5 + 3 = 8 cookies in total. The nth term of the sequence for the basketball players taking cookies in 2n - 1. The number of players is 8 so they would have eaten 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 = 64 cookies. In total Andy had 64 + 8 = 72 cookies to start with before they were all eaten. The answer is 72.
Q: Samuel bought 2 dozen doughnuts and Cathy bought 3 dozen doughnuts. They planned to share the doughnuts evenly with their 8 other friends. How many doughnuts will each of them receive?
A:
Since 1 dozen is equal to 12, then Samuel has 2 x 12 = 24 doughnuts. While Cathy has 3 x 12 = 36. They both have 24 + 36 = 60 doughnuts together. There are 8 friends + 1 (Samuel) + 1 (Cathy) = 10 that will share the doughnuts. Thus, each of them will get 60 / 10 = 6 doughnuts. The answer is 6.
