A partial listing of costs incurred during March at Febbo Corporation appears below: Factory supplies $ 9,000 Administrative wages and salaries $ 85,000 Direct materials $ 126,000 Sales staff salaries $ 30,000 Factory depreciation $ 33,000 Corporate headquarters building rent $ 43,000 Indirect labor $ 26,000 Marketing $ 65,000 Direct labor $ 99,000 The total of the manufacturing overhead costs listed above for March is:

$ 68,000

Explanation:

The total manufacturing overhead costs should include the following heads:

Factory Supplies                                           $    9,000

Factory depreciation                                    $   33,000

Indirect labor                                                 $  26,000

Total manufacturing overhead                    $  68,000

The direct materials and direct labor are not part of the manufacturing overhead. though they are part of the manufacturing costs.

The admin  wages and salaries, corporate headquarters rent and the marketing costs are not manufacturing costs

start by isolating the variable on one side by adding 43w^2 to both sides.   the equation will read:

25w^2+5=0

*subtract 5 from both sides*

25w^2=-5

*divide both sides by 25*

w^2=-1/5

*take the square root of both sides*

w=√(-1/5)

the square root of -1 is i.   the square root of 5 remains √5

the answer is i/√5.

hope this
