Reasoning and answer: Jeff makes a total of 10 * 12 = 120 donuts. Jeff eats 1 * 12 = 12 donuts. After Chris is done eating, there are 120 - 12 - 8 = 100 donuts remaining. Jeff needs 100 / 10 = 10 boxes to store all of his donuts.
The answer: 10

Each person gets 42 cookies / 7 people = 6 cookies. Each person gets 63 pieces of candy / 7 people = 9 pieces of candy. Each person gets 21 brownies / 7 people = 3 brownies. Each person will get 6 + 9 + 3 = 18 desserts.
The answer: 18

In her old company, if she worked for three years, the total number of months she was paid for is 3 years * 12, which is the number of months in a year = 36 months. If each month she was paid $5000, her total earnings in the old company were $5000 * 36 = $180000. In her new company, she is paid 20% more, which is 20 / 100 * $5000 = $1000 per month more than what she was paid at the old company. In total, she earns $5000 + $1000 = $6000 per month in her new company. Since she's worked five months more in the new company than the old company, she has worked for 36 + 5 = 41 months in the new company. The total amount she's earned in the new company is $6000 * 41 = $246000. The combined total for both companies is $246000 + $180000 = $426000.
The answer: 426000
Reverse engineering the question: Cadence has worked for her new company five months longer than she worked for her old company. If she worked at her old company for 3 years earning $5000 per month, and she's now earning 20% more in the new company, calculate the total amount of money she's earned in both companies in the period she's worked for them?


Reasoning and answer: The price of the cheaper pair after the discount was $40 / 2 = $20. The total price of both pairs of shoes $20 + $60 = $80. The final discount was $80 / 4 = $20. The price he ends up paying was $80 - $20 = $60.
The answer: 60

Reasoning and answer: After the first spray kills 50% of germs, there will be 100 - 50 = 50% left. The second spray kills 25%, but 5% have already been killed by the 50% spray, so it kills 25 - 5 = 20%. After the second spray kills 20% of the remaining germs, there will be 50 - 20 = 30% left.
The answer: 30
