they ask for the maximum she can borrow not the quickest time she can repay. If she repays the loan over 30 years she can afford to borrow 130000 repaying $953.89 per month.
these tables are really confusing but I think that thats right- at least i hope that its right

Re: Generl Mathematics Solutions

If you get a result of say 70 or something for this exam, does that become your HSC mark, or does it still get influence by how the state does and how your class does? :S

Thanks for posting the answers :)

Re: Generl Mathematics Solutions

they calculate the standard deviation and the mean, and they get the z score and calculate your final (scaled) mark.

Yeh, your right, its 130, thank god it was worth 1 mark!!!
