Comments:
<Mulder> the economist's response would be
<Mulder> we require the equation for the utility function and production function
<Mulder> so that you can figure out the profit and utility maximising bundle
<Mulder> ^_^
<HT`> 50 cents per item
<HT`> discount of 50 cents per additional item.
<Saqib> (1,5) (2,9) (3,13) and so on, you can suppose some other sequence
<Saqib> I wish to find the function
<jc-denton> morning
<HT`> 3 items would mean 13.5 <- not 13
<HT`> hi jc
<Saqib> hmm
<Saqib> yes
<Mulder> you save fiddy cents here, you go to another shop, and you save another fiddy cents, then you go to the dollar store, and buy yourself something nice!
<Mulder> be a man. do the right thing
<Smad> :P
<HT`> lol
<Saqib> suppose this sequence
<Saqib> 1 48
<Saqib> 2 96
<Saqib> 3 144
<Saqib> 4 192
<Saqib> 5 240
<Saqib> 6 288
<Saqib> 7 335
<Saqib> 8 382
<Saqib> 9 428
<Saqib> 10 472
<Saqib> 11 515
<Saqib> 12 556
<Saqib> 13 594
<Saqib> 14 631
<Saqib> 15 666
<Saqib> 16 699
<Saqib> 17 730
<Saqib> the rate start to change from 7 and decreases
<jc-denton> xahlee_: you have an impressive website
<HT`> give me url :O i wanna see
<jc-denton> http://xahlee.org/
<xahlee_> jc-denton: thanks.
<xahlee_> thanks.
<Mulder> nice chinese name
<Smad> are you watching it now?
<HT`> awesome =3
<HT`> contentwise
<Smad> tapsumbong =
<Saqib> Please anyone consider my question
<jc-denton> Saqib: 10% for the double vol
<jc-denton> ?
<Saqib> jc-denton: please explain more
<jc-denton> as you said
<jc-denton> 11:19 < Saqib> Please there is a question. A seller offers a volume based discount. for example 1 item costs $5, 2 items costs $9. how can I find the discount rate?
<jc-denton> so the item costs 5$
<jc-denton> if you double the items it costs 9 instead of 10$
<jc-denton> which is 90% of the price it would cost w/o discount
<jc-denton> so ..
<_chill> hi #math !
<HT`> hi chill :)
<Saqib> this is only true when the discount rate is constant
<HT`> @jc: basically, for each additional item theres 50 cents discount.
<HT`> yeha?
<Saqib> in my later sequence the discount percentage also decreses
<jc-denton> yes..
<jc-denton> brb
<HT`> k
<HT`> what is your second sequence for
<HT`> what are you trying to figure out
<HT`> o.o or is it a part of the first question
<Saqib> my real sequence is (1,48) ... (17,730). and I wish to find a formula for rate of decrease of percentage of discount
<Smad> is the discount rate polynomial?
<Smad> exponential?
<Smad> constant?
<HT`> hold on :p im a math dumb*** here let me see
<Saqib> Smad: not constant, and I wish to find its variation
<Smad> polynomial?
<HT`> okay its weird
<HT`> 2 * 12 = second number
<dysprosia> i get {{1, 5}, {2, 9}, {3, 14}, {4, 18}, {5, 23}, {6, 28}}
<HT`> (second number * 12) / 2 = third number
<dysprosia> the curve has a kink in it, which is odd
<Saqib> dysprosia: please solve (1,48) ... (17,730) sequence now
<dysprosia> excuse me?
<HT`> he's not a bot you know =_=;
<dysprosia> she
<HT`> oops
<HT`> pardon me .. i mean she *
<Saqib> HT: did you find the solution
<HT`> no, found a weird pattern though.. confused me XP
<HT`> here
<HT`> i found that
<HT`> 1st number * 12 = 2nd number
<Saqib> just think the how does the cost per item decreases
<Saqib> 7 335 47.857142857
<Saqib> 8 382 47.75
<Saqib> 9 428 47.555555556
<Saqib> 10 472 47.2
<Saqib> 11 515 46.818181818
<HT`> (2nd number * 12) / 2 = 3rd number
<HT`> and 3rd number + first number = 4th number
<dysprosia> 3 items would cost (cost of two items) + (cost of one item) = $9
<Saqib> format of this sequence is (number_of_item cost rate_per_item)
<dysprosia> 4 items would cost 2*(cost of two items)
<dysprosia> etc
<dysprosia> if we really wish to extrapolate
<dysprosia> i think extrapolation is wrong to do here, in any case
<dysprosia> i don't know
<Saqib> I don't think this is correct. take a look on the sequence, 8 items cost 382 at 47.75 per item. Now 9 items should cost 382*12/2 which is 2292.
<dysprosia> the only data you've given is the cost of one and two items
<Saqib> dysprosia: sorry, but didn't consider my real sequence
<Saqib> 7 335 47.857142857
<Saqib> 8 382 47.75
<Saqib> 9 428 47.555555556
<Saqib> 10 472 47.2
<Saqib> 11 515 46.818181818
<dysprosia> saquib: don't flood, and i have a scrollback buffer
<dysprosia> and i have no idea how you've gotten those numbers
<dysprosia> let c1 be the cost of one item, and c2 be the cost of two items, then the sequence goes {c1, c2, c2+c1, 2c2, 2c2+c1, 3c2, 3c2+c1,...}
<Saqib> these are cost of items in the format like number_of_items total_cost rate_per_item
<dysprosia> given seven items, how do you get the total cost?
<Smad> i don't think the question is accurate
<dysprosia> well, it is, it's just overly complex
<Smad> there must be infinitely many formulas that fit that sequence
<dysprosia> one can have fun in trying to extrapolate, but i think that's sorta missing the point
<Saqib> I asked my vendor about cost of certain number of items
<Saqib> let me explain what I got from the sequence
<dysprosia> saqib: if 7 items costs $335, can't you get 3 * (cost of two items) + (cost of one item), which is not $335
<dysprosia> or is this to fit a real life situation
<Saqib> the rate_per_item decreases as the number_of_items increases
<Smad> give the rate per item in fractions
<dysprosia> the discount rate, from my working of this, oscillates around 90%, but since the data saqib is giving us looks quite different, that's not the answer to his question
<HT`> its a bit vague actually... needs a lot more info Dx
<Saqib> dysprosia: the discount rate changes from 99.1% and decreases as the number of items increases
<HT`> i mean it should be right.. but it isnt o.O;
<Saqib> Should I tell the website of my vendor??? where you can check it yourself
<dysprosia> ht: going from precisely what was mentioned, it should eventually tend towards 90%
<Smad> doesn't look like a simple equation :)
<dysprosia> ht: that is, the initial question
<Smad> maybe they chose the prices themselves?
<Saqib> There is a gradual decrease in rate per item, i think
<Smad> you can check sloane if you want
<Saqib> Please go to http://www.smartlaunch.com/Webpages/Buy/Step1.aspx and Select Germany
<HT`> wow its an actual situation XD
<dysprosia> Server Error in '/' Application.
<dysprosia> very nice
<Saqib> refresh
<Saqib> you know ASP is a bad language ;-)
<HT`> it is XD
<HT`> i HATE ASP
<dysprosia> this is going to take ages to get enough data :(
<HT`> so much work for simplest things
<Saqib> HT: that why I have collected data for you all
