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
