how do you tell if its reducing balance depreciation or flat rate deprecation?

the way i interpreted the question was that the server depreciated by 20% of its original value each year.

I didn't do Business Maths as a Module in Further last year, but with my Accounting knowledge, I can explain that as each year progresses, the value decreases, right? So thats the reason why you calculate the Depreciation Expense for the CARRYING value of the File Server in each particular year, and NOT the ORIGINAL/HISTORICAL Cost of it.

So when it says "of its value", it means the Carrying Value of it after each year and you Depreciate it off the Carrying Value and not the Historical Cost.

Hope this helps a bit.

To achieve minimum number of days Lisa starts activity D after activity A is completed by John, then she does activity E. By the time activity E is completed, total number of days taken is 3+7+6=16

Then 16+5=21. Therefore D is correct.

I dont understand question 2007 exam 1 linesr graphs  if maximum vlue of z occurs at thrle pploint (100,0)

I dont understand question 2007 exam 1 linesr graphs  if maximum vlue of z occurs at thrle pploint (100,0)

if you sub that point into the objective function Z=200. Now you need to test for possible values of k where (100,0) gives the maximum Z value. If k=1, Z=2x + y. Subbing all the co ordinates in you get that Z is still the maximum at (100,0). When k=2, Z=2x + 2y. If you sub in (100,0) and (50,50) you get 200. You only want one maximum at (100,0) so k must be 1.

Hey cuties,

Let's say I'm given quarterly seasonal indices for rainfall in mm of Summer, Autumn, Spring & Winter.
In terms of describing a seasonal index of ... for Summer, what would you guys use?

The rainfall in Summer is typically:

VCAA 2005 Ex1 q11: '% above the yearly average'
VCAA 2009 q4c: '% above the average for the four seasons of the year'

Most of the commercial papers I've done: '% above the seasonal average'
Essentials Textbook: '% higher than the quarterly average'

I'm a tad confused. Are they all the same/different? Anyone know/have evidence as to what VCAA expects?

Hope you understand the question.
Thanks A LOT!!!

For me, what I do is look at the context. For questions involving 4 seasons, I'll mention seasonal average. For questions Jan-Feb, I talk about the yearly average. Its really not a big deal, just make sure that you are clear about it though!

Hope this helped

[Zealous]

For questions Jan-Feb, I talk about the yearly average.

Monthly average?

[Yacoubb]

Monthly average?

Oops; probably the worst time to make a mistake. Yeah I meant monthly average haha. Thanks for that!

To avoid confusion, just go with seasonal average. Because irrespective of what you're dealing with, it'll be a season.

So for 1.5 for ice-cream sales in December:
Ice cream sales in December are 50% greater than the average seasonal ice-cream sales.

Thanks Yacoubb and Zealous! But then how come VCAA used 'yearly average' in 2005... Is that correct aswell?

Hi, Have a question about seasonal indices.


'Given that the seasonal indices for winter and autumn are 1.41 and 0.92 respectively, then it is reasonable to conclude that'

D) Autumn sales are 8% less than yearly average

E) Winter sales are approximately 35% of the yearly sales

I thought that D would have been the answer, although the solutions say that E is correct,

with explanation:
Winter sales =
(1.41/4)×100=35.25%

I thought it would've been D, as I have an explanation in my book that says if the seasonal index is 0.92, it indicates a performance of 8% below the average.

Thanks

And I've that question aswell, then I saw the VCAA papers so I was like, what?

And there was one question with seasonal index 0.8, to correct for seasonality
(D) increase by 20%
(E) increase by 25%

Answer is E. How?!

[Patches]

You need to add .20 to get to 1, so .2 is 25% of .8
