Q: Henry had 33 games, and he gave five of them to Neil. Now Henry has 4 times more games than Neil. How many games did Neil have at first?
A: After giving five games to Neil, Henry has 33 - 5 = 28 games left. Now, Neil has 28 / 4 = 7 games. Neil had 7 - 5 = 2 games at first. The answer is 2.
Question: Billy is counting the rings in two trees. Weather fluctuations in this area mean that each tree's rings are in groups of two fat rings and four thin rings. If Billy counts 70 ring groups in the first tree and 40 ring groups in the second tree, how much older is the first tree? (Trees grow 1 ring per year.)
Answer: First find the total number of rings in a ring group: 2 rings + 4 rings = 6 rings. Then subtract the number of ring groups in the second tree from the number in the first tree to find the difference: 70 groups - 40 groups = 30 groups. Then multiply that number by the number of rings in a group to find the difference in the trees' ages: 30 groups * 6 rings / group = 180 rings, or 180 years. The answer is 180.
[Question]GiGi took out a big bowl of mushrooms from the refrigerator. She cut each mushroom into 4 pieces. Her twins, Kenny and Karla sprinkled mushrooms on their pizzas and baked them in the oven. Kenny grabbed a handful and sprinkled 38 mushroom pieces on his pizza. Karla scooped them up with both hands and sprinkled 42 mushroom pieces on her pizza. On the cutting board, were 8 pieces of mushrooms remaining. How many mushrooms did GiGi cut up at the beginning?
[Answer]Kenny used 38 / 4 = 9.5 mushrooms on his pizza. Karla used 42 / 4 = 10.5 mushrooms on her pizza. Together, the twins used 9.5 + 10.5 = 20 mushrooms. There are 8 / 4 = 2 mushrooms left on the cutting board. GiGi cut up 20 + 2 = 22 mushrooms at the beginning. The answer is 22.
Q: Bill is laying power cable for a new neighborhood. There are going to be 18 east-west streets that are 2 miles long and 10 north-south streets that are four miles long. It takes 5 miles of cable to electrify 1 mile of street. If cable costs $2000/mile, what is the total cost of cable for the neighborhood?
A: First find the total distance of the east - west streets: 18 streets * 2 miles / street = 36 miles. Then find the total distance of the north - south streets: 10 streets * 4 miles / street = 40 miles. Then add the number of miles from each type of street to find the total distance: 36 miles + 40 miles = 76 miles. Then multiply that number by 5 to find the number of miles of cable needed: 76 miles street * 5 miles cable / mile street = 380 miles of cable. Then multiply that number by the cost of one mile of cable to find the total cost: 380 miles * $2000 / mile = $760,000. The answer is 760000.
Question: Harry is ordering pizza. A large pizza is 14. It costs $2 per topping. He orders 2 large pizzas, each with 3 toppings. He then adds a 25% tip. What is the total cost?
Answer: The toppings on each pizza are $6 because 3 x 2 = 6. The total for each pizza is $20 because 14 + 6 = 20. The pizzas cost $40 because 2 x 20 = 40. The tip is $10 because 40 x .25 = 10. The total is $50 because 40 + 10 = 50. The answer is 50.
Q: John is trying to save money by buying cheap calorie-dense food. He can buy 10 burritos for $6 that have 120 calories each. He could also buy 5 burgers that are 400 calories each for $8. How many more calories per dollar does he get from the burgers?
A:
The burritos have 10 * 120 = 1200 calories. That means he gets 1200 / 6 = 200 calories per dollar. The burgers get 5 * 400 = 2000 calories. So he gets 2000 / 8 = 250 calories per dollar. So he gets 250 - 200 = 50 more calories per dollar from the burgers. The answer is 50.
