It has to be an annuity as he made constant repayments iirc. My value was like $285k or something so he was short about $15k.

Anyone else do the same or am I wrong? I'm probably wrong.

Hayley, 94/100 will probably scale to 9387878439787% dw. I feel like I got about 85% which will scale to low 90's imho depending on how my cohort goes.

I'm not worried about scaling. It's my lowest mark all year because I've been averaging 95-98. Just disappointed because they were stupid mistakes * I wanted a state rank too

Did you use the first present value formula?

yeah whenever you calculate loan repayments you always use present value

So the taxation question, she still owed money? :S
I was confused about the medicare levy...

that question was weird!! I added the levy but i dont know :/

 

[joey95]

Yeah quite confusing
I do remember i wrote she owes $28 but i didn't include the medicare.

Did you use the first present value formula?

I used that formula and worked out the bracket part and got an answer. I then did 300,000 divided by ANSWER.

Then I multiplied that answer by 240 and got that it was somewhere in the $500,000s...

So I said he would be able to pay it off.

Am i wrong..

You might be right and I might be wrong.

I added 250 to the initial M value (her monthly repayments) and then just substituted that into the present value formula with the appropriate numbers. M x (present value formula stuff) gave about $285k so that was how much she would have contributed towards the $300k debt in 20 years. Therefore she didn't make the full amount and whatnot.

Idk.

That question came up in past exams that I did (not sure which, could be CSSA or HSC). In that past exam, they included the medicare levi.

Ah pretty sure I got it wrong then, I swear I tried that but I couldn't get anything to work hah, oh well overall I went okay I thought.

 

[rednellav]

I said she owed money for that question. Fuck.

 

[Fetes]

I said she owed money for that question. Fuck.

Then you would be correct

For the wind speed percentage increase was it a 30% increase or 130% increase?

(not exactly 30, just can't remember what I wrote)

 

[alex122]

are you going to upload the paper?

i hope someone does soon because we aren't allowed to take them
