Question: Stoney Hollow Middle School is taking a field trip to the zoo. There are 109 fifth graders, 115 sixth graders, and 118 seventh graders. There are 4 teachers and 2 parents from each grade coming along to chaperone on the trip. There are 72 seats on each school bus. How many buses are needed for the field trip?
Answer: There are 109 fifth graders + 115 sixth graders + 118 seventh graders = 342 students going on the trip. There are 4 teachers + 2 parents = 6 adults going on the field trip for each grade. There are 3 grades going, so 3 grades x 6 adults / grade = 18 total adults going on the trip. There are 342 students + 18 adults = 360 people going on the trip. So, 360 people / 72 seats = 5 buses. The answer is 5.

Q: Melissa sells a coupe for $30,000 and an SUV for twice as much. If her commission is 2%, how much money did she make from these sales?
A: First find the total cost of the SUV: $30,000 * 2 = $60,000. Then add the cost of the coupe to find the total cost of the cars: $60,000 + $30,000 = $90,000. Multiplying that amount by Melissa's commission rate, we find her earnings are $90,000 * 2% = $1800. The answer is 1800.
Question: Gary manages two Amazon distribution centers. The first center processes 10000 packages per day, and the second center processes three times that volume. If Amazon makes 5 cents of profit per package, how much profit per week do the two centers make combined?
Answer: First find how many packages the second center processes per day: 10000 packages / day * 3 = 30000 packages / day. Then add the packages the first center processes: 30000 packages / day + 10000 packages / day = 40000 packages / day. Then multiply the number of packages by Amazon's profit per package to find Amazon's daily profit: 40000 packages / day * $0.05 / package = $2000 / day. Then multiply the daily profits by the number of days in a week to find the weekly profits: $2000 / day * 7 days / week = $14000 / week. The answer is 14000.
[Question]Karen's students are about to take a standardized test. Karen gets a $500 bonus if their average score is above 75, plus an extra $10 bonus for every additional point the average score increases above 75. So far, Karen has graded 8 tests, and the average is 70. Given that each student can have a maximum score of 150, what combined score do the last two tests need to have for Karen to earn a $600 bonus?
[Answer]First subtract $500 from Karen's goal bonus amount to find how much she makes from the extra $10 / point bonus: $600 - $500 = $100. Then divide the extra bonus by the extra rate: $100 / $10 / point = 10 points. Then add the 10 extra points to the baseline 75 point goal to find the students' average test score: 10 points + 75 points = 85 points. Then added the 8 graded tests to the 2 ungraded tests to find the total number of tests: 2 tests + 8 tests = 10 tests. Then multiply the 85 point average by the number of tests to find the total number of points the students need to earn: 85 points / test * 10 tests = 850 points. Then multiply the current average by the current number of graded tests to find how many points have been earned so far: 70 points / test * 8 tests = 560 points. Then subtract the number of points earned from the number of points needed to find the combine score the last two tests need: 850 points - 560 points = 290 points. The answer is 290.
[Question]Kendy made 2 online bank transactions. She transferred $60 to her mom and half that amount to her sister. As a result, her account now has $100 left in it. How much money was in the account before the transfer?
[Answer]
Kendy transferred $60 x 1 / 2 = $30 to her sister. So, She transferred a total of $60 + $30 = $90. Therefore, Kendy has $100 + $90 = $190 in the account before the transfer. The answer is 190.
