Answer: $1000
Step-by-step explanation:
Hi, the gross margin is equal to the sales revenues minus the cost of the goods sold.
Revenues: inventory sold for $3000
Cost: $2000 Purchase of inventory
So, in this case we have to subtract $2000 (cost) to $3000 (revenue)
Mathematically speaking:
$3000- $2000 = $1000
