Answer:
$258,000
Explanation:
Data given in the question
Salary paid on annual basis to onsite supervisor = $94,000
Salary paid on annual basis to one salaried estimator = $52,000
Two administrative assistant salaries $56,000 and $40,000
Salary of the president = $162,000
So, by considering the above information, the common fixed expense is
= Administrative salaries for one + administrative salaries for another + president salary
= $56,000 + $40,000 + $162,000
= $258,000
