Answer and Explanation:
The computation is shown below:
a. The manufacturing overhead is
= factory utilities + depreciation on factory equipment + indirect factory labor + indirect material + factory manager salary + property tax + factory repairs
= $16,500 + $12,650 + $48,900 + $70,800 + $8,000 + $2,500 + $2,000
= $161,350
b. The product cost is
= Direct material used + direct labor + total manufacturing overhead
= $157,600 + $79,100 + $161,350
= $398,050
c. The period cost is
= Depreciation on delivery truck + sales salaries + repairs to office equipment + advertising + office supplies used
= $3,800 + $48,400 + $1,300 + $23,000 + $4,640
= $81,140
