Answer and Explanation:
The computation is shown below:
Contribution = Sales × Contribution percentage
And, pre tax Income = Contribution - Fixed cost
And we know that
Sales = [Fixed cost+ pre tax income] ÷ Contribution margin
= [$160,000 + $164,000 ] ÷ 25%
= $1,296,000
Now the amount of total variable cost is
2. As we know that
The Variable cost is
= Sales - Contribution margin
= Sales - sales × 25%
= Sales × 75%
= $1,296,000 × 75%
= $972,000
