Step-by-step explanation:
The flexible budget performance report for the year has been solved and attached.
Note that the selling price per unit was calculated as:
= 400,000 /20,000
= $20 per unit
Therefore, total sales was gotten as:
= 26000 × $20
= $520,000
Variable cost per unit was calculated as:
= 80,000/20,000
= $4 per unit
Then, total cost was:
= $4 × 26,000
= $104,000
