Answer:
$5500.
Step-by-step explanation:
The computation of the cost of goods sold is shown below:
Let us assume beginning WIP be $2000 
So, 
ending WIP is 
= ($2000 - $1000)
= $1000 
And, 
Let us assume the beginning finished goods be $1000 
 So, the ending finished goods is 
= ($1000 + $500)
= $1500 
Now as we know that 
Cost of goods manufactured = Total manufacturing cost + Beginning WIP - Ending WIP 
 = $5000 + $2000 - $1000 
 = $6000 
 Now 
cost of goods sold=Cost of goods manufactured+Beginning finished goods-Ending finished goods 
 = $6000 + $1000 - $1500 
 =$5500.
