Question: Anna can read 1 page in 1 minute. Carole can read as fast as Anna but at half the speed of Brianna. How long does it take Brianna to read a 100-page book?
Answer: If Anna can read 1 page in 1 minute, then her speed is 1 / 1 = 1 page per min. If Carole can read at Anna's same speed then her speed is also 1 page per min. If Carole is only half the speed of Brianna, then that means Brianna is twice as fast as Carole, so 2 * 1 page per min = 2 pages per min. If a book is 100 pages long and Brianna can read 2 pages per minute, then it will take her 100 / 2 = 50 minutes to read the book. The answer is 50.
[Question]Sam is twice as old as Sue. Kendra is 3 times as old as Sam. If Kendra is currently 18, what will be their total age in 3 years?
[Answer]Sam is currently 18 / 3 = 6 years old. Sue is currently 6 / 2 = 3 years old. In three years, Sue will be 3 + 3 = 6. In three years, Same will be 6 + 3 = 9. In three years, Kendra will be 18 + 3 = 21. Their total age in three years is 6 + 9 + 21 = 36. The answer is 36.
Q: An online website offers a flat rate shipping price of $5.00 if the purchase is below $50.00. If it's above $50.00 then they will charge 20% of the purchase price for shipping. Thomas orders 3 shirts for $12.00 each, a pack of socks for $5.00, 2 pairs of shorts for $15.00 each and a pair of swim trunks for $14.00 How much will his total bill be, including shipping?
A: He orders 3 shirts at $12.00 each for a total of 3 * 12 = $36.00. He orders 2 pair of shorts for $15.00 each for a total of 2 * 15 = $30.00. He spends $36.00 on shirts, $5.00 on socks, $30.00 on shorts and $14.00 on a pair of swim trunks for a total of 36 + 5 + 30 + 14 = $85.00. His order is over $50.00 so he will be charged 20% shipping on his $85.00 order so he'll pay .20 * 85 = $17.00 in shipping. His order is $85.00 and he's paying $17.00 in shipping for a total bill of 85 + 17 = $102.00. The answer is 102.
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]Out of the 80 students who took the biology exam, only 2/5 of them managed to score 100%. If a score below 80% qualified as failing, and 50 percent of the remaining students who didn't score 100% managed to score over 80%, calculate the number of students who failed the exam.
[Answer]The number of students who scored 100% is 2 / 5 * 80 = 32. Out of the 80 students, 80 - 32 = 48 did not score 100%. If 50% of the students who did not score 100% managed to score over 80%, then 50 / 100 * 48 = 24 students scored over 80%. The number of students who failed is 48 - 24 = 24. The answer is 24.
[Question]James runs a TV show and there are 5 main characters and 4 minor characters. He pays the minor characters $15,000 each episode. He paid the major characters three times as much. How much does he pay per episode?
[Answer]
He pays the minor characters 15000 * 4 = $60,000. The major characters each get 15000 * 3 = $45,000. So he pays the main characters 45,000 * 5 = $225,000. So in total he pays 225,000 + 60,000 = $285,000. The answer is 285000.
