I did a reverse alligations and I came up with 2% also.

My equations would have

2.5----------- Z/1.5 x 45 grams = 30 grams

------------------------------

------------------------------

------ ?P%--------------------

------------------------------

------------------------------

1--------------Y/1.5 x 45 grams = 15 grams

I then solved each equation even though one is enough to prove that

the answer is 2%:

Z/1.5 x 45gm = 30 gms

Divide each side by 45g

Z/1.5 x 45gm......30 gms

------------- = ----------

.........45 gm.....45gm

Leaves:

..........30 gms

Z/1.5 = ------

..........45gm

Multiply each side by 1.5

................30 gms

Z/1.5 X 1.5 = ------ X 1.5

................45gm

Leaves:

.....30 gms

Z = ------ X 1.5 = 1%

.....45gm

Now PLUG this one back into the alligation and check what

?P% would have to be!

If Z/45 is really 1/45 then ?P% must have been a " 2% " , so that 2 -

1 = 1

The above is all that is necessary.

but to be a good summaritan and show or prove the bottom part of the

alligation is true also:

Y/1.5 x 45gm = 15 gms

Divide each side by 45g

Y/1.5 x 45gm......15 gms

------------- = ----------

.........45 gm.....45gm

Leaves:

..........15 gms

Y/1.5 = ------

..........45gm

Multiply each side by 1.5

................15 gms

Z/1.5 X 1.5 = ------ X 1.5

................45gm

Leaves:

.....15 gms

Z = ------ X 1.5 = 0.5%

.....45gm

Now PLUG this one back into the alligation and check what

?P% would have to be!

If Y/45 is really 0.5/45 then ?P% must have been a " 2% " , so that

2.5% - 2% = 0.5 %

So Janet Here is the 'interesting' way that I checked for 2%!!

So many ways to skin a cat! But this is not a reality show!

Now Kris, what book and edition are you using?

Loves yas!

> I too got the answer 2% and here is how.

> First, we must find out how many grams of HC are in each part.

Once we have that done, then we must find out how much HC is in the

total.

> 1gram/100grams= x/15 grams

> x= .15 grams

> 2.5 grams/100 grams= x/30 grams

> x=0.75 grams

> By adding the quantitites together 0.15 + 0.75 we come up with

0.90 grams and 15+ 30 = 45grams

> Now,
