Data for January for Bondi Corporation and its two major business segments, North and South, appear below: Sales revenues, North $ 548,000
Variable expenses, North $ 318,000
Traceable fixed expenses, Nort $ 65,600
Sales revenues, South $ 423,500
Variable expenses, South $ 241,600
Traceable fixed expenses, South $ 54,800
In addition, common fixed expenses totaled $148,600 and were allocated as follows: $77,200 to the North business segment and $71,400 to the South business segment.
A properly constructed segmented income statement in a contribution format would show that the segment margin of the North business segment is:
a. $87,200
b. $318,000
c. $164,400
d. $152,800

Segment margin North= $164,400

Explanation:

Giving the following information:

Sales revenues= $548,000

Variable expenses= $318,000

Traceable fixed expenses= $65,600

To calculate the segment margin for the North division, we need to use the following formula:

Segment margin North= segment contribution margin - traceable fixed expense

Segment margin North= (548,000 - 318,000) - 65,600

Segment margin North= $164,400

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'
