Can anyone figure these financial ones out? I get a different answer on financial solver compared to when I use equations (not sure why).

Thanks

This are the answers I got:

a) 19 months
b) $802.47
c)$802.50

tell me if there correct so I can explain, if not then we'll try and figure them out together.

Those are the answers I got too. But the answers from itute give different answers (They could be wrong, what's your opinion on how they worked it out?)

For Part b ii) Did you use the PMT of -802.47 that gives FV = -0.025... then add it on to the payment to get $802.50 as the final answer? That's how I got it.. Thanks for the help so far!

You used itute answers, no wonder why you got them wrong. My math teacher tells us NEVER to use itute answers, even when he was going through some questions, he released they were wrong because he had gotten a different answer.They are defeinitly right answers.

Yes, for part bi) I solved the future value for 5 years, which was $5501.99, then I put this value in the PV, and then I changed N to 7, and then I clicked on PMT and it gave me $802.47.

bii) I just clicked on future value and I got -0.025 [whih rounds up to -0.03] Then I added this to $802.47, which gave me $802.50

Please help!! I have a question about financial maths

"The price of the equipment, $8360, included 10% GST (Goods and Services Tax). Calculate the price of the equipment before the GST was added."

I know that the answer is 8360/1.1 = 7600, but I am struggling to understand why the answer isn't 8360*0.9 = 7524.

Thanks in advance!!

8360 is 7600 plus 10% of 7600 added on.
7600 + (10/100)*7600 = 7600 + 760 = 8360

Doing 0.9*8360 is like subtracting 10% of 8360 which is not the same as adding 10% of 7600.
8360 - (10/100)*8360 = 8360 - 836 = 7524

10% of 8360 is greater than 10% of 7600. (836>760).

Think of dividing by 1.1 as a shortcut of going backwards algebraically.

Let's say 7360 = x.
100% + 10% of x = 8360
1.1x = 8360

Now, we divide by 1.1 on both sides to find x
1.1x/1.1 = 8360/1.1
x = 8360/1.1
x = 7600

Are questions relating to GST and hire purchase plan  still relevant to the study design?

No they're not

Hi everyone,

For the further exam, is it acceptable to bring in a workbook (my notes throughout the year) and duct tape it to a further maths company notes book? I will make sure that I tape it together very firmly to ensure that the two books won't separate.

Thanks very much

Hi everyone,
Can anyone help me out with the last question in graph and relations module of the 2016 VCAA exam 2?
Thanks in advance!

^^ so long as it adheres to all these requirements you should be fine 
Just remember that if any pages fall out, the exam supervisor will remove it and it will be reported as a breach of rules.

Need help for Graphs and the types of data which are used for each!
Using mainly the Australian Bureau of Statistics and the Cambridge textbook I have made this list of notes; however, when faced with multiple options in exam 1, I sometimes make a mistake as the data can possibly fall within more than one graph and its quite frustrating! So I am looking for someone with the perfect notes who can help me with this issue.

Two-Way Frequency table: categorical data

Bar Chart: Categorical data

Stacked or Segmented Bar Chart: Comparing two or more categorical variables
Frequency Table: Categorical or discrete numerical data

Dot Plots: Categorical and discrete numerical data

Stem and Leaf Plot: Discrete and continuous numerical data

Back to Back Stem and Leaf Plot: Categorical (i.e. Sex) Discrete and continuous numerical data

Histograms: Ungrouped Discrete and continuous numerical data

Box Plot: Categorical and discrete numerical data

8360 is 7600 plus 10% of 7600 added on.
7600 + (10/100)*7600 = 7600 + 760 = 8360

Doing 0.9*8360 is like subtracting 10% of 8360 which is not the same as adding 10% of 7600.
8360 - (10/100)*8360 = 8360 - 836 = 7524

10% of 8360 is greater than 10% of 7600. (836>760).

Think of dividing by 1.1 as a shortcut of going backwards algebraically.

Let's say 7360 = x.
100% + 10% of x = 8360
1.1x = 8360

Now, we divide by 1.1 on both sides to find x
1.1x/1.1 = 8360/1.1
x = 8360/1.1
x = 7600

Thank you so much!!

Hi everyone,

If a question comes up in the finance section of the exam and asks for us to round to the nearest whole number (for payments) must we always round up? For example let's say you get 12.3 payments on the finance solver, do you have to go up to 13 if the question asks to the nearest whole number?
Thanks
