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

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.
