Re: Generl Mathematics Solutions

my answers were similar, but for Q27 A i, isn't it \$80,000.00 over 10 years (120 months) becuase the monthly repayment is \$970.62?

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

Yeh..but it asked whats the 'maximum amount she can borrow' and 130k for 30 years is the maximum she can borrow with her limit.

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

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!!!
