Final answer:
The cost of a hotel room in France is 1 euro and with the 1:1 exchange rate, the cost in dollars is also $1. Therefore, option (A) $1 is the correct answer.
Step-by-step explanation:
The student is asking about the cost of a hotel room in France in terms of U.S. dollars when the given exchange rate is 1 euro to 1 dollar (expressed as £1 = $1 in the question). To answer this, we simply need to recognize that when the exchange rate is 1:1, the cost in euros will be the same as the cost in U.S. dollars. Since no specific euro amount was given for the room, we assume it is 1 euro based on the given exchange rate. Therefore, the cost of the room in dollars is also $1, so the correct answer is (A) $1.
