Distributive property is 
a(b+c)=ab+ac
we can make it easier by splitting up 63 into 60+3
so
7(63)=7(60+3)=7*60+7*3=420+21=441
        
                    
             
        
        
        
Answer:
(6,9) nice
Step-by-step explanation:
 
        
             
        
        
        
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
