Answer:
The $400 is the net profit.
Explanation:
For computing the net profit we apply the equation which is shown below:
Net profit = Sales - variable cost - fixed cost
where,
Sales is $1,000
Variable cost = variable cost per unit × number of unit = $40 × 10 = $400
And we know that sales - variable cost = contribution
So, contribution would be $1000 - $400 = $600
And, the fixed cost is $200
So, the profit would be = Contribution - fixed cost
= $600 - $200
= $400
Hence, the $400 is the net profit.
