Answer:
A. $27,500
B. $20,500
Explanation:
A. The computation is shown below:
= (Fixed cost of Detroit - Fixed cost of Dallas) ÷ (Variable cost of Dallas - Variable cost of Detroit)
= ($780,000 - $560,000) ÷ ($30 - $22)
= ($220,000) ÷ ($8)
= $27,500
B. The computation is shown below:
= (Fixed cost of Detroit - Fixed cost of Dallas) ÷ (Variable cost of Dallas - Variable cost of Detroit)
= ($780,000 - $616,000) ÷ ($30 - $22)
= ($164,000) ÷ ($8)
= $20,500
The Dalla fixed cost is increased by 10%, so the new fixed cost would be
= $560,000 + $560,000 × 10%
= $560,000 + $56000
= $616,000
