202 months

how did you do this.. i did some weird method and im not sure

 

[mikaa]

fuck i got 300 months.

 

[osak23]

you do the same thing for ii) to get the value of m
this equation from ii) < 180000

at the end you switch the signs around due to log being negative

you get n>201.blah blah
therefore n=202

sorry for shit explaination lol..
just try from ii)

wow... l can't believe l got that loan repayments one right!!!!!!
l've struggled in loan repayments my WHOLE school life...
l can't believe this O.O
but it wasn't hard, nor it was difficult compared to the other question 8's and 9's in the past papers. you know they ask the same stuff every year so it wasn't worth revising.

 

[duckysd]
