The answer is 600, I got this by multiplying the two numbers
        
                    
             
        
        
        
Basically, the unit rate is 1.99/18 or 0.110. 
If we round 1.99 to 2.00, we instead get 0.111~

For the answer to the question above asking, w<span>hat was the price per can and the numbers of cans purchased each time?
let x be the number of cans he bought
the let us go to the 2nd statement which is t</span><span>he next time Ian purchased frozen orange juice, the price had increased by $0.10 per can and he bought 1 less can for the same total price.
The equation for this is .10(x-1) = 24
So now let's solve, 
</span> .10(x-1) = 24
.10x - .10 = 24
.10x = 24+ .10
.10x = 24.10
Then divide both sides by .10
So the answer for this question is 
241 cans of juice
        
             
        
        
        
For any arbitrary 2x2 matrices 

 and 

, only one choice of 

 exists to satisfy 

, which is the identity matrix.
There is no other matrix that would work unless we place some more restrictions on 

. One such restriction would be to ensure that 

 is not singular, or its determinant is non-zero. Then this matrix has an inverse, and taking 

 we'd get equality.
