<PRE><B>Question 67374</B>
Pencils sell at D dollars for 1 dozen.  At this price, what would be the total cost of M pencils?

D dollars per dozen-----That means that they sell for D/12 dollars per pencil

If one pencil costs D/12 dollars, then M pencils must cost (D/12)*M dollars

So the answer is:  (D*M/12)

ck 

Lets say D=24 dollars
And M=10

24 dollars per dozen equals 24/12 or $2 per pencil

Then 10 pencils would cost 2(10) or $20

D*M/12=(24*10)/12=240/12=$20  At least it works for these numbers


Hope this helps---ptaylor
