Answer:
-3/2
Step-by-step explanation:
5x+3=3x
Subtract 5x from each side
3 = -2x
Divide each side by -2
-3/2 = x
The number of Euros received against 600 dollars = 450
Then
For 1 dollar, the number of euros = (450/600) euros
= (45/60) euros
= ( 3/4) euros
= 0.75 euros
So the unit rate that describes the exchange rate is 0.75 euros per dollar. So the correct option among all the options given in the question is option "A".
