Question: Liam wants to go to Paris, but first, he has to pay his bills. His trip costs $7,000, and his bills cost $3,500. Knowing that Liam has saved $500/month for 2 years, how much money will he have left after paying his bills?
Answer: Step-by-step reasoning process: In total Liam has saved ($500 / month * 12 months / year) * 2 years = $12,000. When Liam pays his bills, he will have $12,000 - $3,500 = $8,500 left.
So the answer is 8500.

Question: There are 8 men at a yoga studio with an average weight of 190 pounds and 6 women with an average weight of 120 pounds. What is the average weight of all 14 men and women?
Answer: Step-by-step reasoning process: The total weight for the 8 men is 8 men * 190 pounds per man = 1520 pounds. The total weight for the 6 women is 6 women * 120 pounds per woman = 720 pounds. The total weight for 14 men and women is 1520 pounds + 720 pounds = 2240 pounds. The average weight per person is 2240 pounds / 14 men and women = 160 pounds.
So the answer is 160.

Question: 42 raspberries, blackberries, and blueberries were picked in total. If half of all the berries had been raspberries, and a third of the berries were blackberries, how many of them were blueberries?
Answer:
Step-by-step reasoning process: 42 / 2 = 21 raspberries had been picked. 42 / 3 = 14 blackberries had been picked. 21 + 14 = 35 raspberries and blackberries had been picked. 42 - 35 = 7 blueberries had been picked.
So the answer is 7.
