Answer :
Answer: $147,000
Explanation:
Cost of sales is a variable cost.
Selling and administrative costs:
[tex]Variable\ cost\ per\ unit=\frac{Change\ in\ cost}{Change\ in\ activity}[/tex]
[tex]Variable\ cost\ per\ unit=\frac{294,700-273,600}{7,000-6,000}[/tex]
[tex]Variable\ cost\ per\ unit=\frac{21,100}{1,000}[/tex]
= $21.10 per unit
Fixed cost = Total cost - Variable cost element
= $294,700 - ($21.10 per unit × 7,000 units)
= $294,700 - $147,700
= $147,000
