i don't remember it clearly either.
it was 21% and $300 or something and we had to work out the price before the sale <<< I THINK IT WAS SOMETHING LIKE THIS!

 

[cardude456]

i think u had to do 300 divided by (100-21)

 

[cardude456]

for the interest question................ Alex was the one who paid more right......???

 

[shalala]

I wrote Bob :/ but i guessed.
i think you are right

 

[shafayat]

for the interest question................ Alex was the one who paid more right......???

alex was paid 17.5 more

 

[shafayat]

What did u guys get for the simultaneous equation on the last page............?

0.85 0.55 .. but they said to write in 2 dp ...

alex was paid 17.5 more

i got it right.............thanks

it was like ...

(100-21)/100 of X is sumthing

so reverse percentage

sumthing * 100 / 79 = I think the answer was 455 or sumthing like that

Guys the probability question 4/9 for the first one and 14/45 for the second one.

Yeah i did the same
and what length did you get by converting the length in the loci??

remeber 100-29 PERCENT SO 0.81

 

[Naser Al-Ayyoub]

yA THATS CORRECT
