well, here's the thing. i don't actually need your critique on the picture i took, but more over on the logic behind the formulas.
what i needed too do is minimize cost. i took the derivative of each machine's cost function and found it's zeros. since they all yielded a value of +/- i just take the positive number. here is the setup:
i need to print napkins with ensignia's(spelling) on each of them. one logo for the king and one for the queen. i need a cost function for the entire thing so i can minimize cost. i have two machines, an old one and new one. each machine can press 8 plates (napkins) at a time. the plates cost is a one time fee. the machines stamp a certain amount per minute, this doesn't mean it stamps that many napkins a minute, just how many times it comes down to press the plates onto the napkins. in other words, the old machine with all 8 plates would stamp 8*600/min. here is the data:
king:
plate: $100
napkins: 610,000
queen:
plate: $100
napkins: 500,000
old machine:
press: 600 stamps/min
cost: $36/hr
new machine:
press: 800 stamps/min
cost: $42/hr
oh yea, napkins cost: 10cents/piece
since i've been having some trouble with the forum users seeing my images because of hosting issues, it would be nice if someone could throw the pics up on their host as well in case someone can't see it.
Thanks ahead of time for any insight ya math.wizards.
edit----
if you don't know what i'm talking about, i welcome you to critique the photo. :)
