Answer:
The number of whole dumpling does Omar make is 14 .
Step-by-step explanation:
Given as :
The number of cups does Omar has to make dumplings = x = 2
i.e x = 
or, x = 
Again
The number of cups uses for each dumpling = y = 
i.e y = 
Let The number of whole dumpling does Omar make = z
So, number of whole dumpling does Omar make = 
Or, z = 
Or, z = 
Or, z = 
∴ z = 7 × 2
i.e z = 14
So, The number of whole dumpling does Omar make = z = 14
Hence, The number of whole dumpling does Omar make is 14 . Answer

Answer:
$11.50. Each CD cost $11.50.
Step-by-step explanation:
When trying to determine how much each CD cost, we need to know our total cost, $57.50, and how many CDs were bought, 5.
Since 5 CDs cost $57.50, we can divide our total cost by the number of CDs purchased to find the cost of each CD. 57.50 / 5 = 11.50
