You have two binomials. I would just FOIL them:
First: 4 x 2 = 8
Outside: 4 (-√3) = -4√3
Inside: -3√3 (2) = -6√3
Last: -3√3 (-√3) = 9
Addummup: 8 - 4√3 - -6√3 + 9 = 17 - 10√3
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".
I hope the procedure for
getting to the correct result is clear enough for you to understand. In future
you can use this procedure for solving similar problems.
