Answer:
The manufacturing overhead cost during the year=$128,000
Step-by-step explanation:
The manufacturing overhead costs can be calculated using the formula below;
O=C-M
where;
O=manufacturing overhead costs
C=conversion costs
M=material costs
In our case;
O=unknown
C=$728,000
M=$600,000
replacing;
O=728,000-600,000=128,000
O=128,000
The manufacturing overhead cost during the year=$128,000
