Question: The dinner bill for 6 friends came to $150. Silas said he would pay for half of the bill and the remaining friends could split the rest of the bill and leave a 10% tip for the whole meal. How many dollars will one of the friends pay?
Answer: Step-by-step reasoning process: Silas paid half = 150 / 2 = 75. Remaining bill paid by 5 friends = 75 + 10% of 150 = 75 + 15 = 90. Each person will pay 1 / 5 which is 90 / 5 = 18. Each friend will pay $18.
So the answer is 18.

Question: Natalie's father has saved up $10,000 to split up between his kids. Natalie will get half, as she is the oldest. Rick will get 60 percent of the remaining money, and Lucy will get whatever is left after Natilie and Rick get paid. How much money does Lucy get?
Answer: Step-by-step reasoning process: Natalie: 10000 / 2 = 5000$. 10000 - 5000 = 5000. Rick:5000(.60) = 3000$. 5000 - 3000 = 2000$ left for Lucy.
So the answer is 2000.

Question: Abe finds 4 ants on the sidewalk. Beth sees 50% more ants than Abe. CeCe watches twice as many ants as Abe. Duke discovers half as many ants as Abe. How many ants do the four children find together?
Answer: Step-by-step reasoning process: Beth finds 4 + 2 = 6 ants. CeCe finds 4 x 2 = 8 ants. Duke finds 4 / 2 = 2 ants. The four children find 4 + 6 + 8 + 2 = 20 ants.
So the answer is 20.

Question: James takes up dancing for fitness. He loses twice as many calories per hour as he did when he was walking. He dances twice a day for .5 hours each time and he does this 4 times a week. He burned 300 calories an hour walking. How many calories does he lose a week from dancing?
Answer:
Step-by-step reasoning process: He burns 2 * 300 = 600 calories an hour. He dances for .5 * 2 = 1 hour per day. So he burns 600 * 1 = 600 calories per day. So he burns 600 * 4 = 2400 calories per week.
So the answer is 2400.
