Q: A spiral notebook costs $15, and a personal planner costs $10. How much would it cost in total to buy 4 spiral notebooks and 8 personal planners at a 20% discount?
A: If a spiral notebook cost $15, a 20% discount would reduce the price by 20 / 100 * 15 = $3. At a 20% discount, the buying price of a spiral notebook book is $15 - $3 = $12. At the same discount, a personal planner cost would reduce by 20 / 100 * $10 = $2. The new buying price of a personal planner will be $10 - $2 = $8. To buy four spiral notebooks at a 20% discount, you'll pay 4 * $12 = $48. At the same time discount, you'll buy eight personal planners at a cost pf 8 * $8 = 64. In total, to buy eight personal planners and four spiral notebooks, you'd have to pay $64 + $48 = $112. The answer is 112.
Question: A farmer planted 30 rows of tomatoes with 10 plants in each row. Each tomato plant yields 20 pieces of tomatoes. How many pieces of tomatoes can the farmer get from all his planted tomatoes?
Answer: The farmer planted a total of 30 x 10 = 300 tomato plants. Thus, the farmer can get 300 x 20 = 6000 pieces of tomatoes. The answer is 6000.
[Question]Monica and Sheila are twins. Their mother gave them $50 and told them to buy some toilet paper and spend the remainder on groceries. The toilet paper cost $12. They bought apples, butter, eggs, and a large ham for twice the cost of the toilet paper. Since they still had some leftover money, they called their mother and she gave them permission to buy whatever they wanted for themselves as long as they shared the money evenly. They saw some boots they really liked, but a pair of boots costs 3 times the amount they had left. How much more would Monica and Sheila each have to add of their own money to buy two pairs of boots?
[Answer]The groceries cost $12 x 2 = $24. Including the toilet paper, Monica and Sheila had already spent $12 + $24 = $36. This means that they had $50 - $36 = $14 left to spend on themselves. However, the boots cost $14 x 3 = $42 per pair. Two pairs of boots would cost $42 x 2 = $84. They need another $84 - $14 = $70 to buy two pairs. Each of them needs to add another $70 / 2 = $35. The answer is 35.
Q: The bald eagle can dive at a speed of 100 miles per hour, while the peregrine falcon can dive at a speed of twice that of the bald eagle.  Starting from the same treetop, if it takes the bald eagle 30 seconds to dive to the ground, how long, in seconds, will it take the peregrine falcon to dive the same distance?
A: Twice the speed of the bald eagle is 100 * 2 = 200 miles per hour. Let "x" be the time in seconds it takes the peregrine falcon to travel to the ground. Thus, based on the ratio of their speeds, the following expression is given: x = 30 * (100 / 200). Thus, x = 15 seconds. The answer is 15.
Question: Tamika drove for 8 hours at an average speed of 45 miles per hour. Logan drove for 5 hours at 55 miles an hour. How many miles farther did Tamika drive?
Answer: Tamika drove 8 hours * 45 mph = 360 miles. Logan drove 5 hours * 55 mph = 275 miles. 360 - 275 = 85 miles. Tamika drove 85 miles farther. The answer is 85.
Q: The average of marks scored in four tests by Jake was 75. If jake scored 80 marks in the first test and 10 more in the second test, and an equal number of marks in the third and fourth test, calculate the marks he scored in the third test.
A:
Since the average of marks scored in four tests by Jake was 75, the total marks that he scored in the four tests are 4 * 75 = 300. If jake scored 80 marks in the first test and 10 more in the second test, he scored 80 + 10 = 90 marks in the second test. The combined marks for the first and the second test is 90 + 80 = 170. The total marks Jake scored in the third and fourth test is 300 - 170 = 130. Since Jake scored an equal number of marks in the third and fourth tests, he scored 130 / 2 = 65 marks in each of the third and fourth tests. The answer is 65.
