3 should be D I think. He was also paid a $50 wet weather allowance.
For 11, I had D, but that question confused me and I might not be right.

Oh crap...didn't read that.

My working out for 11 was
X=(45000 x 1.06 + 7500) / 12
X = 55200 / 12
X = 4600

Hayley

I did 1.06(45000+7500)/12. Not sure if that's right (mine).

...

Got all the same except for 3) D.

I interpreted the 6% as on the salary alone but maybe I'm wrong

Yea, I don't think they explained it very well.

21 i had A

It didn't specify a gender when choosing. It said "one of these students" So I did 155/505 =31%

"What is the probability that this student is MALE and living with his parent (s)?"

10 should be 155/505 * 100. It didn't ask what is the probability that a male is living with his parents. It asked what is the probability of him: being a male, and that he lives with his parents - as indicated that they "selected by random" and they didn't "select a male."

I feel that is an incredibly awkwardly worded question again.

11 is an awkwardly worded question. I think it might be D actually. Fuck.

21 was tossing up between A or B. I think it is A actually.

10 - oh fuck whoops

11 - Yeah, really depends if it was 6% of salary or all up

 

[Cleverusername5321]

I just looked at 21 again and can't remember if I put A or B. At this point I'm thinking it's definitely A. Dear god I hope I put A.

 

[hayleyemma96]

Can someone provide the working for 21?


Hayley

 

[jasonz1c]

How were you supposed to do Q22 ( the vegetable garden one)?

 

[Hazballs]

21:
S = 800(1 - r)
S = 800 - 800r
S + 800r = 800
800r = 800-s
r = 800 - s/800

= A

 

[Hazballs]

22:
2x + y = 20
Y = 20 - 2x

Area = xy

x(20 - 2x)
20X - 2x^2

Misread two questions and got them wrong...best I can hope for now is 22/25 UWS for me.
