A New Math Dilemma!!!

[smokethedays]

If you have ONLY $20.00 and you must buy with it 20 animals as a mix of the following three animals:
sheep $4.00
chicken $0.50
bird $.25
you have to buy at least one of each kind and the number of the animals you have to buy has to be 20 and worth an even $20.00
so many of each kind will you have?

What the hell kind of math class are you in?

oh no, not another one of these...

im too tired to think right now

only 5 minutes! cmon smoke give us a challenge

Calculus

ahh, gotta love calc

man that was goood, not many people were able to do it.
did u guess it or did it mathematically?

[Superhuman]

what are you in, remedial math?

[caddilac]

actually i used excel. is that cheating?

you mean me?

uhhh, what?

[ilovesus]

I just picked up some BD test E. the hologram on the side that has a BD and the dragon is green? All the pics i looked at there all red. Anyone ever see this?

[ilovesus]

can someone tell me how to post a new thread please?

[smokethedays]

go to the top of this page and look for the tab that says: Anabolic Steroids - Steroid.com / Anabolic Review Forums on the top left, click it and it'll show you all the categories of the forum. choose the one you want and scroll down a bit and u'll see a tab called new thread. click it then type in the topic of ur thread and then the body and click post.

let x = number of sheep
y = number of chickens
z = number of birds and
solve the system of equations

4x + 0.5y + 0.25 z = 20
x + y + z = 20

you will get your answers in parametric form, but we must choose a parameter such that all x ,y ,z values are integers

i will solve it later

you would need one more equation to solve. 3 variables = 3 equations

[stunner5000pt]

you would need one more equation to solve. 3 variables = 3 equations

you can use a parameter for your z varaible

assume z = t, some real number
and go from there

chances are they isnt necessarily a unique solution

or you could use excel like i did

excel is like synthol

mathematica is like testosterone

can u finish solving that way?

oh yea, matrix style solution. good call bro

[OSTIE]

can u finish solving that way?

Like dude says... chances are it may not lead to a unique solution... but since a correct answer has already been posted it should.... but it will get very messy that way....

Is this really from a calculus course??? I already completed my calculus sequence about a 1 and a half to 2yrs ago (I cant remember because I dont attend college regularly anymore) but I dont remember this being part of calc 1... seems more of a pre calc class to me....

I guess if it needs to be solved using an alternate variable.. than it would be calc...

Goes to show... give urself a couple years and you forget everything you learned in school if you dont continue to attend regularly or graduate

[OSTIE]

So off the top of my head.... Solve for 'y' first...

You get y = (56.25/3.5)t

Plug this back in for 'y' in the first equation and solve for 'x'.... 'x' will than equal "SOMENUMBER"t

U place both these values back in the first equation and solve for 't'... once you have the value for 't' you will easily be able to figure out the rest....

caddilac is right. you don't even need a formula to figure this out. my little bro could probably do it!

3 sheep = $12
15 chickens = $7.50
2 birds = $.50
TOTAL
20 animals = $20

Ya, if he had Excel... I doubt a calc professor would except that has a correct solution, because in higher math classes like calc, its not about the answer, its about how you arrived at the answer

[stunner5000pt]

this isnt a calc question... its more of an elementary linear algebra question

[OSTIE]

Ya, im tryin to find some of my old books, but like I said... I thought it was more of a pre-calc class (linear algebra to most).... some schools are different though, so it may be incorporated in a first year calc course as the first chapter or two

[Superhuman]

Well it would be the answer, since he asked "so (how) many of each kind will you have?"

[ilovesus]

thanks bro

I would buy a cow for $20 he has more protein

calculus was more about derivatives and integrals. this kind of problem is more like algebra, but it can be solved using matrices, which is linear algebra.

mmm, steak. i could go for some of that right about now
