Question: Annie went to a liquidation sale and bought 5 televisions that each cost $50. She also purchased 10 figurines. If Annie spent $260 in total, how much did a single figurine cost in dollars?
Answer: Step-by-step reasoning process: Annie spent 5 * $50 = $250 on televisions. She has $260 - $250 = $10 left for the 10 figurines. A single figurine costs $10 / 10 = $1.

Question: Markus is twice the age of his son, and Markus's son is twice the age of Markus's grandson. If the sum of the ages of Markus, his son, and his grandson is 140 years, then how many years old is Markus's grandson?
Answer:
Step-by-step reasoning process: Let "x" be the age of Markus's grandson. If Markus's son is twice the age of Markus's grandson, then Markus's son is 2 * x. If Markus is twice the age of his son, then Markus is 2 * 2 * x. Therefore, if the sum of the ages of Markus, his son, and his grandson is 140 years, then x + (2 * x) + (2 * 2 * x) = 140 years. Simplifying the equation, we see that 7 * x = 140 years. Therefore, the age of Markus's grandson is x = 20 years old.
So the answer is 20.
