A student is traveling out of the United States to visit family living in Europe.

This problem involves currency conversion. The exchange rate states that $1 equals €1.2. To convert euros to dollars, divide the euro amount by 1.2. Set up the calculation: €120 ÷ 1.2 = $100. Therefore, the cost per night in US dollars is $100. Option C is correct. Option B incorrectly multiplies instead of dividing. Options A and D fail to account for the exchange rate. NEX math problems involving currency emphasize understanding the direction of conversion and selecting the correct operation.
