    Actually, Tach happens to be correct for the particular case of "cost" = cost price and "price" = sales price (or vice versa)

    Yes, Tach is an abrasive and stubborn ass who can't admit to his mistakes, his original post was nonsense, and I don't know if he's yet acknowledged the consumer interpretation of "cost"="price", but for the particular interpretation of cost and price being different values, he is correct.

    No, it explicitly stated:
    i.e.
    Cost = $1 + Price/2


    Half its price.
    No, he said it's $1 plus half its price.

    If someone says "The cost is $1 plus tax", they don't mean "The cost is $1".

    Consider this conversation:

    Buyer: "What's the cost?"
    Seller: "$1 plus tax."
    Buyer: "How much is tax?"
    Seller: "Half the price."

    ...

    Where to from here?

    If the seller means that the total selling price is $1 plus tax, and that tax is half the total selling price, then $2 is the only answer that works, right?

    -"What did it cost you this wonderful book?"
    -"Six bucks."
    -"Where you bought?"
    -""From the corner bookstore. He went into liquidation and now it costs half the price plus 1 bucks.This wonderful book which is priced $ 10, cost me only 6 bucks.I am very happy."

    An attempt at posing the question unambiguously.

    Buyer: What is the price of that book?
    Seller: Well, I bought it at 60 cents and I was going to sell it for $1, but now the taxman says he wants half of whatever I sell it for. What price should I sell it at to make the same profit for me, 40 cents?
    Buyer: Aw, shucks, I don't know, I'll ask sciforums. They's intelgenced people there ah hear.

    @Deicider
    Does that pose the question of the OP, or not?

    If so, $2, close thread, goodbye.
    Or perhaps not.

    This thread is a new plane on a conveyor belt, but with algebra.

    This is where common sense outdoes logic every time.
    I'd have put "The question doesn't make sense", and got no marks.

    Because comprehending what is intended by the question is as much a part of any test as is the correct answer.

    Based on the OP, in order to get any sort of answer to this question, the assumption is that price == cost, as it would for any person trying to buy the book. There is no valid grammatical reason to assume that price != cost in this case. The only reason people argue it is because they don't want to admit they were wrong.

    Until the OP actually comes back with what is the right answer, I suppose were gonna be debating this. I swear this is some sort of sociology experiment intended to see how long it gets debated. It would Explain why OP has remained silent, dismissed one answer and not confirmed or given any proper answer.

    No, reread it Pete.
    That's not quite what I said.

    Yes, that corresponds to the other interpretation, where "cost" and "price" can be different values.

    For the person trying to sell the book, cost != price is a reasonable interpretation.
    But as you say (and as Tach has said), that interpretation provides no answer.

    I don't understand what you're getting at, Dywyddyr?

    Playing with the actual wording.
    The word "cost" is used twice, on one of those occasions the cost is stated to be $1. The other use asks what is the cost.
    Just messing about.

    There is proof the book never cost $1.00:

    From the OP, it was always a $1.00 + 1/2 of cost

    The cost is not mentioned, but is not impossible to deduce it's total amount, with the partial data given.

    And it was deduced successfully at $2.00

    The cost could never have been a total of $1.50 and a total of $1.00, simultaneously.

    Huh?

    "Clever/innocent tricks" are never a sign of advanced intellect. I'm talking about this OP.

    (I'm relating this to the "clever/innocent tricks" used elsewhere on this forum, with the word Keffir, and the use of the swastika symbol, as well.

    Playing with the wording doesn't mean ignoring clauses.
    The cost is explicitly stated to be $1 plus half the price.

    Messing about or not, [post=2701067]post 106[/post] is just wrong.
    Don't go all Tach on us!

    I have noticed some similarities.

    There is enough data to conclude the cost/price, equally as to what huh would leave us to conclude about you.

    Huh? How so?
    Cost = x, price = y.
    Who me?

    I was pointing out Tach's error with his assigning X and Y. He wasn't consistent.

    It depends on whether or not you've read all my posts in this thread, and understood the intent of the, er, less than serious ones.

    Okay, friendly fire then. It's difficult to get accurately irritated at boneheads, when there are so many intellects around, equally irritated as well, just emanating that frustration in a different manner. I must keep that in mind. Thank you.

    Wow how many days is this going on? LOL

    Ok so there are 2 "Real" Possible answers:

    $2 in which case cost == Price

    OR

    y=x/2+1 which is the graph of a line with a y intercept of 1 and a slope of 1/2.

    There is no reason to assume that the second condition is correct. And as a matter of everyday parlance the use of cost == price is common enough to make the first assumption.

    $1 and $1.50 are both wrong, and have no way of being correct.

    You can read the OP like this:

    y=1+x/2

    For x=1, y=1.5 . This is a very bad business
    For x=2, y=2 . Still a very bad business
    For x>2, y<x . This is more like it' the business starts being profitable.

    Or, you can read it like this:

    x=1+x/2, so x=2 . The same bad business as above.


    Or, you can read it like this:

    Cost=1$

    The trademark of an ill-posed problem is that it is open for interpretation.

    Only a very stupid businessperson would sell at cost.

    Depends on your blinders.

    But I was deadly serious about "Christmas Cake" as a possible answer.
