Answer:
a. $45,800.
Step-by-step explanation:
The computation of the common fixed expense not traceable is given below
Combined segment margin of two divisions ($42,800 + $29,900) $72,700
Less: net income -$26,900
Non traceable fixed cost $45,800
Hence, the amount of the common fixed expense not traceable to the individual divisions is $45,800
Therefore the option a is correct
