First time on MO here, I am SO guy... any ways.
I'm working in global trade stuff and we buy a lot of units such as 1000 units of this thing.
If we buy 1000 units the price is 7.50 per unit and 7.00 per unit for 2000 units.
Sorry about this non math term stuff but can I get an equation to get the price for any given unit amount considering it scales based on number of units.
so if 1001 units = 7.49, if 1050 = this etc...
Sorry - first title got the prices mixed up :(
I checked out the faq and this is not the place for "Homework Questions" like the latter. So I won't post stuff like this again.
Answer 1) ((price_high - price_low) / difference_in_units) - this was just a guess.
Answer 2) Take the price difference between the highest and lowest unit costs and then divide that by the highest number of units.
ex: 7.50 - 7 / 2000 and this will give you a percentage that needs to be multiplied with the number of units and added to the number the lowest price.
