Answer:

(n^2 + n)/2 ways

Explanation:

Each time you can climb 1 or 2 steps to the top (n steps)

Number of ways climbing 1 step to the top = n combination 1 = n!/(n-1)1! = n(n-1)!/(n-1)! = n

Number of ways climbing 2 steps to the top = n combination 2 = n!/(n-2)!2! = n(n-1)(n-2)!/2(n-2)! = (n^2 - n)/2

Total number of ways = n + (n^2 - n)/2 = (2n + n^2 - n)/2 = (n^2 + n)/2 ways

Kostelnik Corporation uses a job-order costing system with a single plantwide predetermined overhead rate based on machine-hours
balu736 [363]

Answer:

The correct answer is B.

Explanation:

Giving the following information:

Estimated overhead= $285,600

variable manufacturing overhead= $2.70 per machine-hour

Estimated machine-hours= 42,000

Job A496:

Number of units in the job 20

Total machine-hours 80

Direct materials $910

Direct labor cost $1,820

First, we need to allocate overhead to Job A496:

Estimated manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base

Estimated manufacturing overhead rate= (285,600/42,000) + 2.7

Estimated manufacturing overhead rate= $9.5 per machine hour

Allocated MOH= Estimated manufacturing overhead rate* Actual amount of allocation base

Allocated MOH= 9.5*80= $760

Now, we can calculate the total cost:

Total cost= 910 + 1,820 + 760

Total cost= $3,490

Finally, we determine the unitary cost:

Unitary cost= 3,490/20= $174.5

Annual Depreciation expense= $58,800

<em>According to International Accounting standards(IAS) 16 property plan and equipment (PPE), the cost of an asset is the purchase cost plus other costs of bringing it to the intended working conditions.</em>

Cost of assets = 300,000 + 14,000 + 40,000 =$354,000

Annual depreciation = (Cost - Scrap Value)/ Number of years

                                   = (354,000 - 60,000)/5

                                 =$58,800
