Final answer:
D) They all have the same amount of money.
The question lacks information on transactions to determine which of the three friends, Larry, Moe, or Curley, has the least amount of money at the end of the week. We cannot ascertain who has the least without additional details.
Step-by-step explanation:
The question "Three friends, Larry, Moe, and Curley, each begin the week with $20. At the end of the week, which of the friends has the least amount of money?" does not provide enough information to determine who has the least amount of money at the end of the week.
The question lacks information on transactions to determine which of the three friends, Larry, Moe, or Curley, has the least amount of money at the end of the week. We cannot ascertain who has the least without additional details.
Each friend starts with the same amount, and without additional data on how they spent or received money during the week, it is impossible to conclude whether Larry, Moe, Curley, or if they all have the same amount of money now. In order to answer this question, we would need more specifics on the transactions that each friend made throughout the week.
