Question: The teacher agrees to order pizza for the class. For every student in the class, she will buy 2 pieces of cheese and 1 piece of onion and they will eat exactly that amount. A large pizza has 18 slices. She orders 6 total pizzas and there are 8 pieces of cheese and 4 pieces of onion leftover. How many students are in the class?
Answer: Step-by-step reasoning process: Cheese pizzas are 2 / 3 of the pizza's purchased because 2 / (2 + 1) = 2 / 3. She buys 4 cheese pizzas because 6 x (2 / 3) = 4. These give her 72 pieces of cheese pizza because 4 x 18 = 72. The students at 64 pieces of cheese because 72 - 8 = 64. There are 32 students in her class because 64 / 2 = 32.
So the answer is 32.

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: Step-by-step reasoning process: 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.
So the answer is 180.

Question: Kimberly went strawberry picking with her family over the weekend. She picked 8 times the amount of strawberries her brother picked and her parents picked 93 strawberries less than her. If her brother picked 3 baskets each containing 15 strawberries, how many strawberries would they each have if they divide the total number of strawberries equally amongst them?
Answer: Step-by-step reasoning process: Kimberly's brother picked 3 x 15 = 45 strawberries. Kimberly picked 8 x 45 = 360 strawberries. Kimberly's parents picked 360 - 93 = 267 strawberries. Altogether, they picked 45 + 360 + 267 = 672 strawberries. Each of them will have 672 / 4 = 168 strawberries.
So the answer is 168.

Question: Sally and Bob have made plans to go on a trip at the end of the year. They both decide to work as babysitters and save half of what they've earned for their trip. If Sally makes $6 per day and Bob makes $4 per day, how much money will they both have saved for their trip after a year?
Answer:
Step-by-step reasoning process: Saly saves 1 / 2 * $6 / day = $3 / day. Since each year have 365 days, the total amount of money Sally will save in a year is $3 / day * 365 days / year = $1095 / year. Bob saves 1 / 2 * $4 / day = $2 / day. The total amount of money Bob will have saved in a year is $2 / day * 365 days / year = $730 / year. In total, Sally and Bob would have saved $730 + $1095 = $1825.
So the answer is 1825.
