Module 4 Business Maths Discussion: How'd you guys find it?

[sam.utute]

how did u get the last q D?
i got E

TVM Solver:
N = 2
I = 5
PV = -4000
PMT = -800
FV = ?
P/Y = 4
C/Y = 4

Therefore answer is D

I made a stupid stupid mistake on 8. I went for A and not for B. I first had B and then changed it since I thought wait it might be four years. Blahh kicking myself now stupid mistake -__-, Hope i can still get a 40 or close to it.

question 6 is B not A

[johsephhh_]

guys Q5 30000*(.8)to the power of 3 so C
Q6 is MINIMUM  MONTHLY BALANCE so 1450*1/12*3.6 divided by 100 so A

oh FUCK your right !

6/9 for bus math damnnnn
6/9 for matricies
8/13 for core
6/9 fr number pat

26/40
= 65%

What do I need to get on exam 2 to get 35? can anyone help?

(Sacs were all over 75%)

I thought about using the TVM solver for that question but having not be familiar with this topic I had only previously used it to answer the PMT (I decided to do this instead of Trig last night).

I ended up going 4000 x 1.05 + 800 = 5000
then 5000 x 1.05 + 800 = 6050 which gave me E.

I am guessing you use the TVM solver to work out q8 as well? I couldn't figure out how to do that one either. Other then those two I had all the same answers as you.

You needed to divide the 5% p.a. by 4 to get the quarterly interest rate. Other than that, your working is correct.

Nah, TVM is useless for Q8.
Basically, 40000-22000 = 18000
That's how much depreciation over 3 years, so that's 6000 per year.
Express that as a percentage over the cost price:
6000/40000 x 100 = 15%

By far the easiest module, way easier than the previous years. I went through the nine questions in 5 minutes, no joke. Everything was pretty much explanatory D:

Ah of course, what a silly mistake.

Ah cheers, pretty easy question as well.
I didn't really know how to approach this one so I did 40000 x each of the interest rates but another silly mistake by me was reading it was a flat rate.

Anyways, thanks for showing me how it's meant to be done.

I got a few differences
Q9-B and Q5-B
can someone explain these answers.

Q9 is above.

To get the answer to Q5 I did:
after 1st year = 30,000 x 0.8 = $24,000
after 2nd year = 24,000 x 0.8 = $19,200
after 3rd year = 19,200 x 0.8 = $15,300 = C

You would have done the first year correctly figuring it out it drops by $6,000 but then you have to get 20% of the number after this first year which is 24,000 rather then multiplying $6,000 by 3 then taking it away from $30,000.

Guys i think question 5 is B....
The file server depreciates by 20% of 'its value' each year

doesnt 'its value' = 30000 so since 20% of 30000 = 6000

30000 - 6000x3 = 12000 = B?

30000 - 6000x3 = 12000 = B?

i wnent with C because it says "its value each year"

so i went 30 000 X 0.20 = 6000
30 000 - 6000 = 24 000
24 000 X 0.20 = 4800
24 000 - 4800 = 19 200
19 200 X 0.20 = 3840
19 200 - 3840 =
15 360 = C

I hope it's right, its the difference between a B+ and an A for me basically

[zxcpoi123]

It's pretty confusing whether it's " its value....each year " or " its value of each year"

i hope they figure something out or just give everybody a mark

win win for both of us xD
