If the exchange rate between the Euro and the U.S. dollar is $2.50 to €1, how many dollars would be needed to purchase a plane ticket costing €1,580?

• A. 3,800
• B. 3,950
• C. 4,500
• D. 4,900

Answer: (B)

Converting currencies using the given exchange rate. The rate of $2.50 per €1 means each euro costs 2.50 dollars. To find how many dollars are needed for €1,580, multiply the euros by the rate: 1,580 × 2.50 = 3,950. So you would need 3,950 dollars to purchase the ticket. A quick check helps ensure the result makes sense: more euros require more dollars, and 3,950 dollars buys exactly €1,580 at this rate. The other amounts would correspond to different euro totals (for example, 3,800 dollars would cover €1,520 at this rate, and 4,500 dollars would cover €1,800), not €1,580.
