And for letter I, I have 100

- jim_thompson5910

so far so good

- jim_thompson5910

what else?

- anonymous

Oh wait nevermind D cant be 15 cuz at the end it says 40 ppl like hatchbacks

- anonymous

Oh wait! B is 40 then right?

- jim_thompson5910

you already said D = 10

- jim_thompson5910

B isn't 40

- anonymous

Oh so where does the 40 go if A is 15?

- jim_thompson5910

`There are 40 people who liked hatchbacks`
this goes in the "liked hatchbacks" row and "total" column. Basically saying "the total of people who liked hatchbacks is 40"

- jim_thompson5910

ie, C = 40

- anonymous

Oh so B is 25?

- jim_thompson5910

yes

- anonymous

Because 40-15= 25

- anonymous

ok

- anonymous

G=25... H=60....F=45

- anonymous

right?

- jim_thompson5910

G = 25 ... correct
H = 60 ... not correct
F = 45 ... not correct

- jim_thompson5910

you may have mixed up H and F somehow?

- jim_thompson5910

but the values don't swap (not entirely)

- anonymous

No cuz 25+35= 60

- anonymous

@jim_thompson5910

- anonymous

I am confused now...

- anonymous

I thought E was 35 and B was 25....35 + 25= 60?

- jim_thompson5910

hint:
G+H = 100

- jim_thompson5910

another hint:
C+F = 100

- anonymous

Oh ok

- anonymous

Ok so can we just review that....
A=15
B= 25
When we add those two we get C=40
D=10
E=???
What did we say E was? is it 50? when we add 50+10 we get F=100
G=25
H=i guess 75, if e is 50
25+75 is I=100

- jim_thompson5910

F is not 100

- anonymous

Oh i meant 60 sorry

- jim_thompson5910

G+H = 100
25+H = 100
solve for H to get H = 75

- jim_thompson5910

F = 60, correct

- anonymous

cuz 50+10 is 60...

- jim_thompson5910

or you can solve for F in
C+F = 100
40+F = 100
either way, F = 60

- anonymous

So would this be the chart?

##### 1 Attachment

- jim_thompson5910

perfect

- anonymous

Uh lol ok thank you now part B

- anonymous

So the number would be 50, right? And then we divide that by 100. so 0.50 or 50% is that right?

- jim_thompson5910

you have to consider the totals for those who don't like hatchbacks or sedans

- jim_thompson5910

number who don't like sedans OR hatchbacks = (number who don't like sedans) + (number who don't like hatchbacks) - (number who don't like both)

- anonymous

Oh so 75 or 75%

- jim_thompson5910

close but no

- anonymous

I thought it was the total?

- anonymous

25% ?

- jim_thompson5910

number who don't like sedans = 75
number who don't like hatchbacks = 60
number who don't like both = 50
number who don't like sedans OR hatchbacks = (number who don't like sedans) + (number who don't like hatchbacks) - (number who don't like both)

- anonymous

Ohhh! okk so...

- anonymous

85%

- jim_thompson5910

yes

- anonymous

ok wow I finally understand this now?

- jim_thompson5910

the subtle difference is that 50% would be if it said "what percentage didn't like BOTH types"
or "what percentage didn't like sedans AND hatcbacks". They didn't just hate 1 car. They hate both cars.

- anonymous

Ok i get it now.

- jim_thompson5910

in part C, you simply compare the values of H and F

- anonymous

so then it would be yes

- jim_thompson5910

yes since H > F

- anonymous

I cant thank you any more! I have one more question.. i am going to open it up in a few minutes
