Answer: positive cross elasticity of demand.
    
Explanation: In simple words, cross elasticity refers to the degree of change in the demand of a good with respect to change in the price of another goods. 
In case of substitute goods, one good can easily be used in the place of another good. Thus, if the price of one good increases the demand for its substitute good also increases. 
Hence from the above we can conclude that substitute goods have positive cross elasticity. 
 
        
             
        
        
        
I think now I’m present day that money is now being transferred online and email services I think cash for no longer be used in the future because the rise of technology and how everyone is now getting so used to it and depending on tech
It would be positive it would be more clear to people and for the younger generation to learn about but for the older generation it would be much harder and would be a negative affect on them since they didn’t use technology in their days and a lot of people are still used to cash

Answer:
Y=38.8 
Y will increase by 38.8
Y=246+38.8
Y=284.8
Explanation:
Y=A. F(K, L)
Y=A. K^0.3, L^0.7
Then 
Y=246
A=1
K=2000
N or L=100
Solutions 
200=1(2000^0.3, 100^0.7)
Now the question says both k & N are increased by 0.20
Therefore 
Y=1(2400^0.3, 120^0.7)
Y=1(10.3 + 28.5)
Y=38.8
