Answer:
hello your question is incomplete attached below is the complete question
answer : 
For Negative cross-price Elasticity : 
DVD players and DVD and Shampoo and conditioner
Positive cross-price Elasticity :
Beer and Wine  and  Soda pop and iced tea
Zero cross-price elasticity :
Coffees and shoes 
Explanation:
<u>For Negative cross-price Elasticity : </u>
DVD players and DVD and Shampoo and conditioner ; this is because the percentage change in the price of any of the good will affect the demand for both goods negatively or positively
<u>For positive cross-price Elasticity :</u>
Beer and Wine  and  Soda pop and iced tea : The percentage change in the price of any of the good will affect the demand of the other good positively ( increase in demand of the other good ) 
<u>For Zero cross-price Elasticity </u>:
Coffees and shoes; The percentage change in the price of any of the good will not affect the other because both goods are not related

Answer:
0.69
Explanation:
Given that we have the formula for calculating income elasticity of demand as the percent change in quantity demanded divided by the percent change in income, hence, we have the percent change in quantity demanded => 13 - 12 = 1 ÷ 12 = 0.083
the percent change in income => 280 - 250 = 30 ÷ 250 = 0.12
Therefore we have => 0.083 ÷ 0.12 = 0.69
Hence, the final answer is 0.69
