\[(w)(c)=$ \]
OpenStudy (chrisplusian):
so
OpenStudy (anonymous):
hmm
OpenStudy (anonymous):
dw/c?
OpenStudy (chrisplusian):
\[$/(c)=w\]

OpenStudy (anonymous):
hmm
OpenStudy (anonymous):
answer choices are 100dw/c
OpenStudy (anonymous):
dw/100c
OpenStudy (anonymous):
100cdw
OpenStudy (anonymous):
$/(c) = w is right.

OpenStudy (anonymous):
dw/c
OpenStudy (anonymous):
and cdw
OpenStudy (anonymous):
Mhmm..
OpenStudy (anonymous):
c and E are nonsensible
OpenStudy (anonymous):
since this problem is going to deal with division

OpenStudy (anonymous):
right?
OpenStudy (anonymous):
so, dollars times whistles/100c?
OpenStudy (anonymous):
dw/100c?
OpenStudy (anonymous):
you there?

OpenStudy (anonymous):
could you help me out chlorophyll?
OpenStudy (anonymous):
Could you explain how I should tackle this problem?
OpenStudy (anonymous):
just do ratio, don't forget to convert dollar into cents
OpenStudy (anonymous):
what do you mean?
OpenStudy (anonymous):
like, 100 cents equals a dollar?

OpenStudy (anonymous):
Is that what you are trying to say?
OpenStudy (anonymous):
Number of whistle = d dollar * W/ c cent
= 100 C * W/ C
= 100 W
OpenStudy (anonymous):
ok?
OpenStudy (anonymous):
ehh
OpenStudy (anonymous):
100dw/c

OpenStudy (anonymous):
thats the answer, but why?
OpenStudy (anonymous):
I understand where we got the 100 and dollars from
OpenStudy (anonymous):
so, since each whistle costs c cents, we have to divide?
OpenStudy (anonymous):
we have to convert from cents to dollars
OpenStudy (anonymous):
so we got 100dw/c?

OpenStudy (anonymous):
am I correct?
OpenStudy (anonymous):
Is my reasoning correct?
OpenStudy (anonymous):
you there, Chlorophyll?
OpenStudy (anonymous):
x/ d = W/ c
->( x/ 100 c ) = w / C
OpenStudy (anonymous):
100d times whistles/c
Join the QuestionCove community and study together with friends!
Sign Up
OpenStudy (anonymous):
so my reasoning is correct?
OpenStudy (anonymous):
=> x = 100C * W/ C
= 100 Whistes
OpenStudy (anonymous):
k...
OpenStudy (anonymous):
so am I right?
OpenStudy (anonymous):
No more d, because d is convert into 100 cents

OpenStudy (anonymous):
but
OpenStudy (anonymous):
answer booklet states A as the answer
OpenStudy (anonymous):
100dw/c is the correct answer
OpenStudy (anonymous):
100 times 2 dollars equals 200 dollars
OpenStudy (anonymous):
200 times 2 whistles equals 400 dollars

OpenStudy (anonymous):
If the book use d as unit, so yes!
OpenStudy (anonymous):
400 dollars divided by 50 equals 8 dollars
OpenStudy (anonymous):
cents becomes a whole number
OpenStudy (anonymous):
so
OpenStudy (anonymous):
we got 100 times 2

Sign Up
OpenStudy (anonymous):
which is 200
OpenStudy (anonymous):
times 2 whistles is 400
OpenStudy (anonymous):
divided by 40 is 9
OpenStudy (anonymous):
8 I mean
OpenStudy (anonymous):
Are you asking the same question?

Okie!
