Question: John starts at an elevation of 400 feet. He travels downward at a rate of 10 feet down per minute for 5 minutes. What is his elevation now?
Answer: Step-by-step reasoning process: He traveled down 10 * 5 = 50 feet. So he is at an elevation of 400 - 50 = 350 feet.
So the answer is 350.

Question: Abigail spent 60% of her money on food, and 25% of the remainder on her phone bill. After spending $20 on entertainment, she is left with $40. How much money did Abigail have initially?
Answer: Step-by-step reasoning process: Abigail had $20 + $40 = $60 left after paying her phone bill. The $60 is 100% - 25% = 75% of the remainder of her money after spending for food. Since 75% is $60, then 1% is $60 / 75 = $0.80. Thus, Abigail had $0.80 x 100 = $80 left after she spent money on food. The $80 is 100% - 60% = 40% of her original money. So 1% is $80 / 40 = $2. Therefore, Abigail initially had $2 x 100 = $200.
So the answer is 200.

Question: Cilia wants to buy a multi-level dumbbell system. The first pair of dumbbells are 3 lb weights, the second pair is 5 lb weights and the third is 8 lb pounds. How much does the entire system weigh?
Answer: Step-by-step reasoning process: The first pair of weights weighs 3 lb each so all total they weigh 2 * 3 = 6 lbs. The second pair of weights weigh 5 lbs each so they weigh 2 * 5 = 10 lbs. The third pair of weights weigh 8 lbs each so they weigh 2 * 8 = 16lbs. All total, the entire system of weights weigh 6 + 10 + 16 = 32 lbs.
So the answer is 32.

Question: Emily has 6 marbles. Megan gives Emily double the number she has. Emily then gives Megan back half of her new total plus 1. How many marbles does Emily have now?
Answer:
Step-by-step reasoning process: Megan gives Emily 6 * 2 = 12 marbles. Emily then has 6 + 12 = 18 marbles. Emily gives Megan 18 / 2 + 1 = 10 marbles. Emily has 18 - 10 = 8 marbles now.
So the answer is 8.
