It's not true.

A refrigerator keep the cool temperature by moving the heat from inside the box to outside the box.
If that student open the door, the temperature inside the refrigerator would be equal with the average temperature of the room, which make his effort pretty much pointless.

Elza [17]

Answer:

Yes it should as the net present value at the firm WACC is positive $ 4,156.54

Explanation:

we are given with the after-tax cost for the machine and after-tax cost of the labor cost savings the new machine will provide

So we should check if the present value of the savings is greater or equal than the machine cost:

C \times \frac{1-(1+r)^{-time} }{rate} = PV\\  

C $ 8,000

time 10 years

rate=WACC= 0.1

8000 \times \frac{1-(1+0.1)^{-10} }{0.1} = PV\\  

PV $49,156.5368  

Net present value:

inflow - cost

49,156.54 - 45,000 = 4,156.54

olya-2409 [2.1K]

Answer:

B) = $38.44

Explanation:

<em>Activity-based costing is a form of absorption costing where overheads are charged to product using cost drivers. Under this method, overheads are first analyzed and categorized by the activities responsible for them and then charged to product based on the amount of benefits enjoyed using cost drivers.</em>

Activity rate is calculated as:

<em>Activity cost for the period / Total cost drivers for the period</em>

<u><em>Activity rate for supporting customers:</em></u>

<em>The appropriate cost driver to allocate supporting customer activity is the number of customers as given.  This is so because it is most likely that the number of customers served will be a major factor that influences the supporting customers activity costs. </em>

<u><em>Activity rate for supporting customers </em></u>

= Supporting customers overhead/total number of customers

= $34,600/(600+300)

= $38.44
