How much of the original 250 US dollars does Phelan now have? Round to the nearest cent.1 European euro = 1.3687 US dollars

Answer
A
44.70 US dollars
B
73.06 US dollars
C
136.87 US dollars
D
140.41 US dollars

Explanation

Since 1 euro equals 1.3687 US dollars, the 150 euros Phelan spent were worth 150 × 1.3687 = 205.305 US dollars. Subtract that from his original 250 dollars: 250 − 205.305 = 44.695, which rounds to 44.70 US dollars. The correct choice is 44.70 US dollars.
