Oh, this sounds like fun:

The averaged Cost to members is $8
The membership Value for the post office is $18
And the Expense to go from Family to Open is $28
(or from $1Youth to $15Youth With MA is $14)

I think I see your point.
But I still would like to see the formula that mathed out to $18.

What is your opinion of how much dues should go up for a $1 Youth that decides to add the magazine? Being that the averaged cost to magazine getting members is $8.57 (magazine $net / # magazines sent). I like that $8 figure because it doesnt require us to say $6 is being taken from all AMA members, including taking $6 from the $1 dues collected from Youth No Mag members. Folks that take $6 from a $1 check sent in are not my kind of math users.

Would we be ripping off the $1Youth if we charge them $15 for $1Youth + $8.57 Magazine?
How much should we charge the $1Youth if they want a magazine that cost recipients $8.57?
