Answer and Explanation:
The computation is shown below
Total average cost + total variable cost = total cost
Let number of output be x
So,
Total fixed average cost = x × $30
Total variable cost = x × $15
Total cost = $2,500
Therefore,
$20 × x + $30 × x = $2,500
50 × x = $2,500
x = 50
Now the total variable cost is
= 50 × $20
= $1,000
And, the fixed cost is
= 50 × $30
= $1,500
