I got A) 18

at 15 donuts the rate is $1/donut; thus, 12*1 = 12

add 3 donuts becomes $0.83/donut *12 = 10

Thus $2 less per dozen when you add 3 free donuts!

18 it is.. it took me a bit long b/c i did it the traditional way.

final = initial
(n+3)(P-1/6) = nP
solve for n, P = 15/n

ans 15+3 = 18

--------------------------------------------------------
anyways, one verbal question here..

the statement says "..then gave Jim 3 extra donuts for free to make .."
is it right to say "for free", it's free man, thus "for" is redundant. ain't it?

is there any place where we use "for free" logically?

i didn't wanted to start verbal issues here, but.. consider this one from CNET:
"The Massachusetts Institute of Technology is making its course materials available to the world for free download"

this seems logical, is n't it?

"for free" is perfectly fine. In fact, "for free" actually describes that situation better than "free doughnuts" because if they were "free doughnuts", one might infer that the donuts were free all the time whereas the donuts, which normally have some cost, were given away in this instance "for free" implying that this was a specific instance.

Are you okay with this, man?

Akamai,

I used to believe the same way until I hit the following:
-------------------------------------------------------------------
For Free :

Free is an adjective. The expression for free is nonstandard.
Use free or something like for nothing instead.

Incorrect: We got it for free.

Correct: We got it free.

Correct: We got it for nothing.
--------------------------------------------------------------------

in the example above, the author sweetly modified "for free" with "for nothing".

anyway, the usage is still not clear :( . what shall we prefer in the gmat?

I don't know what your source is but "we got it free" sounds like you set a trapped animal loose. Getting something "for free" is so widely used that it has become IMO standard just through usage. Getting something "for nothing" IMO has a stronger connotation than getting something "for free" since "for free" IMO often implies monetary costs only.

But rather than subject you to just my opinion, let me quote Mirriam Webster's Ninth New Collegiate Dictionary, pg 490, as an idiom under the definition of "free":

тАФfor free: without charge

yes, there is no second thought that we have accepted "for free" 's usage as is. even, I used it, the same way, all the time, without askance.

neway, i got the explanation on: https://englishplus.com/grammar/00000209.htm
