mr. russo exchanged 200 euros (european money) for 270 dollars. how many dollars would he get for 300 euros…

Answer:

D. $405

Explanation:

Step1: Find exchange - rate

Let the exchange - rate be $x$ dollars per euro. We know that when 200 euros are exchanged, 270 dollars are received. So, $x=\frac{270}{200}=1.35$ dollars per euro.

Step2: Calculate dollars for 300 euros

If the exchange - rate is $x = 1.35$ dollars per euro, then for 300 euros, the number of dollars $y$ is $y=1.35\times300 = 405$ dollars.
