A certain book is for sale in both Belize and Brazil. In Belize, it sells for 80.39 Belize dollars. In Brazil, it sells for 63.6
bixtya [17]
A book is sold in Belize for 80.39 Belize dollars.
In Brazil, it sells for 63.65 Brazilian reals.

The exchange rate of US Dollars to Belize Dollars is 1:1.9246
<span>The exchange rate of US Dollars to Brazilian Real is 1:1.7880
</span>
If we convert the two into dollars,
Belize Dollars 
1 : 1.9246 = X : <span>80.39 
1.9246X = 80.39
X = $ 41.77 

</span>Brazilian Real
1 : 1.7880 = X : <span>63.65 </span><span> 
</span>1.7880X = <span>63.65 </span><span>
X = $ 35.60
</span>
Difference = $ 41.77 - $ 35.60
Difference = $ 6.17

So, in Belize the book is more expensive by $ 6.17
